Today, almost 3/5 of all forums are just general poop! " A bit of everything, The Chat General Club, etc" people, if you want to go to one of those, then do it! Don't make your own, cause it has been done so many times, it makes you sick when you think what idiots sign up to new ones :P
Now, for the issue; people are makeing forums every day, and the thing is, they are just copying others or makeing it for no reason -_- Also, forums should contain quality content and information about certain topics. If you cannot do that, then just go to one of those forums with experienced people and with a lot of members. It is OK to join forums with stuff you need, but don't waste your time makeing your own forum if you do not know what the hell you are doing.
Sorry, its just kind of sad how so many people are makeing these dumb attempts.
