Create members ? Should I do it ?

I think adding only a few members yourself to start your board off is fine. Just register about four accounts, create multiple topics, and log in and out of the different accounts to form conversations between them. That way when people join your forum, they will see a few conversations already taking place, and the site will look a little more popular.

yea however i was thinking of adding more than 4 lol .. maybe like 50 or so .. cause i already have 77 registered

One always might endeavor to incorporate into one's website such content and keywords that interested parties would have occasion discover the content via websearch, then visit the website to add to or comment on that content - an odd thought, perhaps, but one which seems somehow logical.
