Hello. With that section, all threads are validated by moderators so that's normal - so when you post the thread you'll just have to wait for a mod in that section to get online and see it, before they decide to approve or disapprove it, is all - if they decide the latter they tend to give a reason as to why. The thread will not show up nor be able to be posted in until they approve it as well.
BTW I can't approve it though, as I'm not a mod in that section - so I'm unable to see it and be able to approve stuff in that section in the first place. >_< Hope that helps?
