I dont mean to be rude, and this is just my opinion, there are way too many forum sites out there.
You need to include something extra to make your site successful - for example, frihost offers web hosting.
A forum alone, to me, is not a website.
I would like to advice you to get more and more visitors and posts in your forums.
You have to give the visitors a reason to join your forum. As it is now it gives people nothing because they now that there is many more forums out there where they can discuss this kind of things. People see that there is no activity.
like richard270384 said. You can offer something special. As it is now it looks like a forum that it is no modifications on and it might look like it is not finnished.
thanks.I had in mind to put search engine submission in the forum.please could some one tell me where to get free scripts like that of frihost that can be used to bill per post.
