I knew it the second I hit submit and so submitted another correctly right after. It's the 2nd time I've done that in 15 years. :-) Not too bad I guess. Looks like it's been permanently deleted now. Unfortunately there is no "delete" once you hit submit even though it hasn't started primality testing yet. That would be a nice feature.
