There is no problem - you must participate in the beginner or main sections of the forum to build up a few posts (minimum 5 posts, I believe) before you can post in some of the other sections.

READ the forum rules - if you have something to sell, place a Paid ad in the marketplace. You are not permitted to post your links and ads in the discussion sections.

Promoting links and services (for free) as you did in a previously deleted post can result in being banned from the Warrior Forum.
