Unlike most blog posts, this one is actually wiki-related. It should be fine (but if you have other questions, leaving a talk page message for an admin is more suitable).

Signatures are built with HTML and wiki markup. Instead of explaining those two in detail, I'll go over the basics of operating a sig: With the framework out of the way, your signature should be fully functional. Now all you need is the actual signature. You can try writing one yourself (with HTML and/or wiki markup), or you can adopt and/or alter a signature created by someone else. You should always obtain permission before using someone else's signature. My signature is up for grabs, as is Monchoman45's]. I don't know of any others, personally, though you can always ask around.

 * 2) Another page that transcludes your signature should also be kept in your user space. For example, at User:SirSwify/Sig. Typically, this page will contain . What this does is transclude your signature while passing an unnamed parameter] (this parameter is your timestamp). The purpose of using this transclusion page is so that the entire code of your sig isn't loaded onto a page every time you use it (increases page size, irritating for users of the source editor).
