lol - I wasn't entirely serious - Smaller fonts make it a little cleaner so you know it is a sig, rather than part of the message and doesn't take up so much space.
I mentioned it as something enaberif could add to his list as some people find the small fonts just as hard to read
Maybe we could use some of the area in the screenshot below for people to have their system specs. Since this is a hardware site and pretty much all of the signatures are just people's specs it would cut down on the size a lot and that space is just being wasted for empty space currently.
