Many times I've been sat on the main parent forum for example, 'web development' and have created a thread that was meant for the 'php' forum by accident.
As a result it doesn't really get noticed. I don't think the users should be able to do this. They should be forced to pick a relevant forum -unless their question doesn't include any of the sub forums - which, let's be fair happens at most 5% of the time.
Thoughts?
