Forum:Signature problems

I've noticed that a lot of people have fancy signatures, but some aren't coded properly, so it messes up the text below. I've already noticed such cases on Forum:Ultimate Star Wars Game, where some signatures messed up the numbering and the font due to unclosed/malformed tags. Can we try to make the signatures compatible regardless of the surrounding code? For example, another common problem is the "|". It's normally fine, but when used in templates such as in the Alliance of Fanon, it is taken as a parameter separator and screws up the rest of the stuff below it. So for such characters,  tags would be beneficial. G .He (Talk!) 18:30, 3 January 2007 (UTC)
