The forums now have a feature that disables post editing after two weeks. That said, this feature takes effect in the advertisements board as well. If you are unable to edit your post at any time, either post in this thread with your postlocked advertisement or go ahead and message myself or a global moderator and we'll go ahead and reset the post timer for you. Just so everyone knows, the current timer is set at two weeks. This is not a thread to argue or question the existence of the edit timer, so please refrain from doing so.
Thanks, and happy advertising!
