No, it does not take 6 posts. It takes up to 10 minutes after reaching the requirements until the new permissions are granted.
I did registration and 7 posts yesterday, however, spend only 40 mins on forum, now, day later I`ve got 1:15 on forum, 7 posts and still newbie. The topic I wanted to post to is already too old.
That's life in the digital world lol
