Hi, I have a website (eboarding.net) that is a pretty big website and has user base of 10,000 registered members for the community and email services. I recently found a good domain name that was open (skateboarding2.com) and registered it. Now the thing I am wondering if is it would be a good idea to change names from eboarding.net to skateboarding2.com. Should I make skateboarding2.com go to Eboarding.net or vice versa? Also would it be a good idea to maybe merge the 2 sites together? Like have it so users can choose to have a skateboarding2.com email account or eboarding.net account? Just wondering.

Thanks everyone!
