Should the tilde symbol (~) be used to sign your name? It seems quite commonplace on Internet forums but I don't believe I've ever seen it used in books.
In Wikipedia, four tildes are used to sign a post. This character sequence will be recognised by the software and turned into the user name and a date stamp. This does not mean that a tilde is a valid character to sign your name elsewhere, web or paper.
in the mathematics language the tilde means "equivalent to", so at the end of a signature it may not be proper. However it still looks nice I don't see anything wrong with it can't hurt to stand out and be creative, right? Also, what if it looks to some like it means you're equal to everybody. . . if you perceive it that way? Were all one anyway and if u put it after a smiley it looks like a funny goatee:)~
