Getting “Exceeds posting limit” message

You may still get the error - it is a measure to curb automated spammers. And I still get it occasionally when I am trying to post again too soon after the previous one. The general limit is 30 seconds between posts.

This happens at Level 1. I guess it's done to avoid too many posts by lower level users. Don't worry, as soon as you reach level 2 you can post to your heart's content but I know that it does get annoying after a while.
