I am planning to start my new forum, I hope I will launch my forum with in some days, What you guys think what is the benefit of being a forum owner.
It really depends but you get to create a community of people in a niche where you can sell products to. Try mixing in the forum with an email list, blog, and Twitter acct. Marketing across multiple channels can help.
You can also monetize your forums with adsense links, text links, banners, etc.
Its a business that requires your time, and money. If succeeded you earn money thats the only benefit.
the biggest benefit is that you will make a lot of money if it succeeds. But forums require massive attention and money to get going
Back links are another reason is you have other sites its worth while putting links in your footer 3000 threads = 3000 back links etc.
Forums take up a lot of bandwidth which is a down side.
3000 worthless backlinks that amount to less than a single backlink on a PR1 page. Do the math, run the PageRank algorithm. 1/300th of the average PR of a forum page (having an average of over 300 links per page like SitePoint’s forums), and the average PR of each individual thread being ~0, amounts to nothing.
If what you’re suggesting actually worked, everyone would be PR10 just by producing millions of pages on their own domains linking to their homepage. It doesn’t work like that.
To get back on topic, the benefit is in customer engagement and branding, mostly. Think about how SitePoint benefits from this community. Daily exposure to their brand increases the likelihood you’ll buy their products. You recognize their books on a store shelf.
I never mentioned page rank! back links are a way for search engines to find new content, I had a forum had a page rank of 3 that made my other sites gain in pr anyway.
Why do you need 3000 footer links just to let a search engine find new content? Linking them from ONE page would do the same thing.
3000 is better than 1 plus if sites are linking to pages out side of your homepage it helps!
The benefits from being a forum owner are a greater amount of interaction with your customers and audience. The key thing to consider is that if you want a forum to be successful, you really NEED to have an existing website, business and audience to be able to cultivate such a community. If you have the existing customers, the forum allow you to interact with them and you gain greater loyalty to your brand and (even better), a model for expanding and improving upon what you offer. However if you are simply creating a forum on a certain subject out of the sake of it (especially if forums exist for that topic) - don’t even bother. Without an existing audience you won’t gain the exposure of people joining (en-mass) and therefore, getting the forum kick-started will prove next to impossible as there will be neither the audience or the attraction of high quality contributors. You will end up like 99.99% of the forums on the web with an empty or near dead community as those who did join, found no-one contributed or answered threads (due to lack of activity) and therefore they never return. Essentially it’s a case of a “kick-start” social medium where you need a heavy interaction base to ensure it’s long term viability - like many things in life, it’s not something you can just do on a whim, it requires hard work. 
Sorry but that comment is absurd. Having 3,000 links pointing at your own website (on one forum) is no better than 1 link pointing to yours… do you honestly think Google are ignorant enough to base the quality of links simply upon how many URL’s directing to your website exist? At most they would acknowledge that domain A links to domain B (no matter how many references there are) and the quality of domain A decides how relevant or useful it’s likely to be on domain B. To say that one website which is linked to from the BBC (for example) on one occasion will not be as good as a forum which has 3,000 links back to your website (even though the source isn’t of a high quality) is quite frankly a direct contradictory of logical sense. Quality and PageRank are determined on the quality of the source of the information… this is often proven by the lack of “good karma” having your link spammed across social networks, link pharms and directories hold. I think you need a reality check, claiming that pharming backlinks will be beneficial to your website is stupid. It’s not quantity that matters, it’s the quality of the links.

hit the nail on the head. 
Forum is the easy way to increase a traffic.
Create a forum can give you a platform to communicate with others and let visitors know about your site.
It is an easy way to win targeted traffic for your site.
This to me is the vital part. Its hard work but its a great way to maintain contact within a tightly moderated and controlled environment with your clients.
I am also planning on starting a forum soon.
Forums are incredibly difficult to get going and to run compared to other promotion techniques.
I’d put forums very low on the “easy” ways to increase traffic.
It’s need some time to promote your forum has high pr, if your forum pr is low, you can get nothing.
Having a forum is by no means an easy way to make money or increase traffic. If your website targets an area of interest that a lot of people want to talk about, then maybe you have a lucrative future ahead of you, but don’t just create a forum thinking that people will join just to join. You have to think that they can go to 100 other forums before yours - so what makes yours unique?
