Got closed and migrated to SF after I cast the 5th close vote. But counting mine, there were only 3 votes to migrate it to SF. There was one vote to migrate to SU, and another for Off-Topic I think.
I think I saw somewhere that you need 5 votes under the same category to successfully close a question. Or is that just not the case?
