Want to set up your official ANN thread here?
The best thing to do is to purchase Copper Member
(link given above) to remove newbie restrictions. If you don't prefer that way then either
a) hire someone to post for you or
b) wait for your rank up. If you're not in a rush, then choose the latter or just avail the copper member so you don't have to hire someone and will have the full control of your ANN thread.
