I'm wondering if it's possible to change the location of the signature. By default, Thunderbird (and traditional email format) puts the signature after the quote in a reply and under a line of "-- " (two dashes and a space). At the moment, I can't find a setting that says place signature after quote in reply. If I add the delimiter "-- " to my signatures, everything after that line will be treated as part of the signature, including the quote.
