No you can post there before lvl 25. You can only make 3 replies in 24 hours, they cannot be more then 1000 characters long (you can edit to add more) and you are not allowed to open any topics till your lvl 25, to which you get 1 new topic in 24 hours for you to open. Then as you level up in game (granted if you ever get into the game with error 1017 and so on) you will gain more posts to use in 24 hours with a maximum of 20 posts every 24 hours at lvl 50.

You can post freely though in new player help and technical issues area.
