they can just post what it is they or the customer are trying to do and the misbehavior they're seeing or the error message.

"is there an issue with the latest release?"

"i've got a customer that just upgraded from version A.B.C to X.Y.Z and the <specific feature> configured in <specific way> trying to do <specific thing> is failing with <specific error message>, could this be a regression or did something change deliberately?"
