for custom overlays to be accepted?

I was curious since I submitted one yesterday morningish. First time using the feature.

From 24hrs to 2 weeks or so? There's no set time as it depends on the availability of staff members. You can fill a ticket if you think its taking TOO long, but usually being patient works

Thank you for replying. :) I more curious then anything else.

Just to slake your curiosity...

The last time I submitted an overlay, it took about ten days for it to be approved. It wasn't because there was anything wrong with it; the person doing the approving was just busy. (I had submitted a ticket because I was afraid I might have done something wrong, and the staff was very gracious to let me know what was going on!)
