When you want to join a forum what do you first look for? What is the first thing that usually attracts you to or keeps you away from a forum? Lastly, what keeps you posting and active there?
When I first look to join a forum. I'll check the community and see if it's actually one I want to be a part of. I hate joining forums that have a lot of arguments and has members that do not respect the forum.
If the forum looks good, in terms of design, that is what usually attracts me to it first of all. If it doesn't look good, it won't keep my attention for very long.
I'll stay active at the forum if the discussions are good and the community is polite/friendly. Obviously you will get he odd 1 or 2 members who are not as nice, but that's to be expected.
