Well... the Skeezyks is no authority on the subject of what is, or what isn't, allowed here on MSF. But to my knowledge there is no limitation on the numbers of threads per day a member can post in each section.
With that said, though, it is my personal opinion that one can overdo it to the point where other members just stop replying especially if most of the threads are on similar topics. So, I think there's a "fine line" between not posting enough so that other members start to forget about you (something I'm guilty of) and posting so many threads that other members start to tire of replying to so many threads posted by the same member. "Moderation in all things" is the maxim that comes to mind here. At least these are my
personal thoughts on the subject.
