I think this should be in Questions, but I'll be happy to answer it anyway.
As I understand it, the posting limit is basically so that people don't flood the forums with their own work. If you have a lot of things you could post, why not compare them and just post the best? Or you can spread them out over a period of time. And remember: the more you review, the more people will review you!
If you have any more questions, feel free to PM me.

"It is curious how often you humans manage to obtain that which you do not want."
AquaMarine's right about the reason--so the whole forum isn't flooded by posts from one author. Unfortunately, the limit doesn't go up; it stays two per day. That's not so bad, though. If you have more than two, just post which you think are more ready, and work on editing the others a bit. Or, in the meantime, check out others' work, review (those are, like Amy said, always appreciated,) and check out groups and articles.
Take care!

Vanadis and Aquamarine have already answered this question very well. I just wanted to add that the limit is also there to help you. If you post too many works at once, then that's a very good way of ensuring nothing you wrote will be read. By limiting it to just two at a time, you improve your chances of having your work read.
