Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
Just a quick shout-out to recognize Sean Maher (a.k.a. Smasher) as iPhoneDevSDK's new Top Poster. A community member since July 2008, Sean's added an average of four new posts *every day* since he signed up.
Smasher - thanks for everything you do to make iPhoneDevSDK the best indie forum for iPhone developers on the web!
(hat tip to Kalimba for pointing that Smasher had claimed the title)
