I was just perusing the Badges ( http://ask.sqlservercentral.com/badges ) here at Ask, and came across the CLEANUP Badge. What does First Rollback mean and how does one do that?
I think it relates to when you edit a question and then undo those changes. A bit like ROLLBACK TRAN !!
I was able to get the badge after clicking rollback. Rollback did not appear until after somebody else edited my question.
Thus it appears that you do not have the option unless it is your own question or it is a community WIKI.
