Adding Forum Scripts to a Wordpress Blog

Hello everyone, I’m new to this forum so thanks in advance for your help.

I’m currently trying to develop a custom Wordpress theme for a blog. However, in the future we hope to integrate a forum into the site and develop a community etc.

My question is whether it is is possible to run a free forum script such as SMF in a Wordpress environment?

I gather I’m going to need to use a CMS but am not sure if this will create problems when it comes to launching a forum.

I hope this makes sense and is in the right section and any help appreciated.

Nice 1;)

You can use a custom theme for both. I have seen several but all are commercial themes. You need to pay for them.
