It varies depending on if Yung or I are on the forum. If we are - now watch I'll probably get this wrong too - but from what I've seen so far is it should be almost immediately once it is approved. Worst case scenario is that it runs on the same time table (cycle) as the new member thread approvals which is every two hours. I know others have had to wait longer because I was at work or sleeping.
