My only complaint is the "one attachment per post" thing. Heck, that sucks whan you have a lotta pics so I don't even do it anymore.
If get bored sometime,go to vbulletin .org this is the forum the site managers use. Interesting stuff on there.Sometimes you just think a forum is slow to certain people.Research it and find out why it may be slow to you.It certainly opened my eyes.Some bulletin board software is really tough to get used to. Most people know vbulletin, as there are so many of them.
