Display reasons why user doesn't have permissions to post

[motomac]

When the setting Minimum content count to post is set in a forum user simply doesn't understand why he can't post there. There is no any tips or explanation that he needs to reach N posts to be able to post in this forum. It confuses users a lot. They simply refuse from further attempts because they think this forum is not for them forever.

My suggestion is to add an explanation and to clearly indicate why a user can't post here and what should he do to be able to post.
