Signatures

[BuddyEthridge]

One request, one question:

There needs to be a way to delete signatures. Currently, if I remove all information from body and title, it saves it as 444 on 1.9 and will not let me save in 2.0.

Also, should we redirect users back to the main page when they save changes to the signature? If not, we should at least put in the "changes saved" verbiage at the top of the page. Also, I noticed that when I saved a signature a second time without making any changes, it set it as my default signature, even when I did not check the "default" box. Just something else to look at :).
