We moderate all new users because we are constantly under attack from spambots posting obscene material, so we have to filter it out to make sure it doesn't reach the forum and our customers. As a result you have to make a certain amount of posts, earning a certain amount of points, before your posts no longer need to be approved. This is purely to combat the spam and obscene material that would otherwise infect the support forums.
Monday to Friday we have several moderators actively checking and approving new posts throughout the day consistently. On weekends there may be a slight delay in approving new posts, but we still check the forums at least several times a day on the weekend.
I approved your post before i went to bed last night, you can find it here.
