I've admined a few sites, and even when working, dumping a few "problem children" accounts has been trivial, and no need to wait or delay . . . YMMV, I guess . . .
Were it me, the cleanup would have come first . . . Unless the software on this site really, really blows, it should not have taken all thatl ong (but then again, I didn't see the full scope of the problem). If I want a guaranteed ship date, I'll use Mouser (and pay for it accordingly)
