You have been manually whitelisted by a moderator. If you couldn't before, you can now post normally. Various limits have also been reduced (but not eliminated).

This means you do not have newbie restriction I guess. Say thanks to that mod  
We have a newbie jail which do not allow you to post in-between certain period of time after you made your last post.

I don't think they brought back the newbie jail. That was a board I think they used to be restricted to.

This is restrictions on how often you can post or PM, I assume in an effort to stifle spam bots. It's kind of like getting a beginner's driver's license, then having the restrictions lifted after some time.
