Private Messages Replying and Signatures

Just two minor annoyances in the Private Messaging section.

1. Replying to topics: There doesn't appear to be a way of replying to a PM without quoting the message, which if the PM is long, can be a pain in the butt, ok you can CTRL-A and delete it, but how about a "quick reply" option, much like in the forum itself?

2. Signatures: I think I'm on to my third year of asking, but given that I've yet to receive feedback on it, I'll ask again.. PLEASE give us an option to not include signatures in PMs.

Thanks.
