I'm a long-time lurker, even if I don't post that often, and I was just updating my profile. My signature was four lines long and every time I try to update it limits me to a single line, so for the longest time I just kept the old one. Today I took the plunge and revised it anyway, dropping down to a single line.
I understand the need to limit signatures so that they don't become absurd, but I like to add in a quote or something meaningful and not just a "this is me" at the bottom. Of course, having made this change I guess I can never go back to my old four-line version.
Why are signatures limited to one line?
