I ran across an interesting signature line on this answer:
God bless you, a Catholic Priest.
In general SE sites are pretty strict about not including signature lines in posts. However, the fact that this one identifies the OP as someone with some knowledge on this subject seems like a valuable piece of information. Note that I edited out an intro line from the answer already, but I didn't want to throw away the signature.
Is there a good way to edit this bit of information into the post itself? How should we prompt the OP to handle this in the future?
