Previously only files required manual approval, but since we've noticed a trend of empty projects showing up or attempts to be malicious, we've added manual approval for projects as well.
What does this mean to you?
Basically, you have to wait for an administrator to approve your new project (and as usual, your files). We're available pretty much all the time, though. So it shouldn't be a problem. If you feel we're slow, feel free to stop by IRC and poke us. Try poking Zyuu first, if it's regarding approvals.
