For starters, why post here using such large text?
As for the forum, each forum has a title and "subject" added beneath the title, if you want to make this look more professional, either take your time reading each title/subject and getting the text errors fixed. By this I mean you have so many sentences showing, some words have capital letters while others don't, it just doesn't look right as it is now.
Why have a forum titles Banned Users? IMHO, that forum should be deleted.
I realy can't be bothered naming the room for improvements there.
The forum is a scroll shows, too many forums etc.
The skin, the adverts, it just annoying.
Good luck with it though.
Umm ya way to many forums for a forum of that size. Maybe condense it down then expand as you get more active.
Then also maybe change the theme or customize it more.
No offensive, are you a kid? "We apologies" If your going to be a success, use the correct spelling and wording for what you mean
