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.
I've noticed that, essentially on a daily basis, my app climbs roughly 20 places in the US chart only to absolutely plummet during the hours Americans are asleep. Obviously people aren't buying it during the night, but surely none of the other apps are being bought either... the ranking should stay level. The only thing I can think of is that the other apps are older than mine and have thereby built up a kind of "reputation" that the ranking algorithm takes into account. Anyone have any insight into this phenomenon?
