The first thing I thought when I saw this section was "oh no, let the lurker wars begin!". In all fairness, though, I thought the concept of a lurker was someone that wasn't a member of the forum who basically waits until a set of codes are posted and grabs one if they possibly can, all the while not leaving their footprint anywhere on the forums. Here the situation is even worse. If you're not a member you can't even read these threads, which means "lurkers" here have to be registered members of the forum. To that I say "come on!" If you can take the time to register and take the time to put a promo code into iTunes or the App Store on your device, you can surly take a moment to post a "thank you" to the developer.
This does three things:
1. Makes the developer feel appreciated
2. Lets other members know a code is gone (if you can post the code you took, even better)
3. Prevents every promo code thread from becoming a thread where people moan about "all those darn lurkers and I couldn't get a code <mumble, grumble>".
This was one of the things that annoyed me most about a certain other really popular forum that I'm a member of, and I don't want to see this happen here as well.
Thanks for reading, and sorry for the PSA
