There have been a couple of threads recently that refer to signatures in forum posts. Descolada couldn't wait until he was no longer considered a "newbie" so he could have a signature (hope you don't mind me bringing that up, Descolada!) and I read a few other posts that said something like, "Duh! I was only joking - didn't you read my signature?!"
Personally I can't stand signatures, and turning them off is the first thing I do when signing up to any forum. They're full of annoying animated emoticons, and even if "There are 10 types of people: those who understand binary and those who don't" was funny the first time I saw it, it reaaaaallly isn't funny the 256th time.
So... I just wondered what other people thought about them. Do you have signatures turned on? Do they offer you an insight into other people's personalities even if you don't like them?
