That means you not have to make 50 Posts in the Newbie Area cause you are whitelisted.
Longer answer for those who don't know:
In response to the spam posts yesterday from new accounts a Newbie Forum was created and that is the only place "new" (under 50 posts) accounts can post to start. There's a sticky in it for requesting to be white listed. I had been on the forums here for about 10 days, hadn't been trolling, had made a transaction and was listed under trusted traders... so I guess that's enough to be white listed (requested it last night and had it this morning).
So far the troll posts seem to be much fewer in number today.
