I'm not listing all the possible tags: just the ones that show at the bottom of the page when you go to make an entry, so these are the html tags you can use on this site.

I think the reason the angle brackets on the xmp example don't show correctly is because doesn't permit html to display. I'll fix that.<br /><br />I don't know why Big, blockquote, q, small, sub, and sup are showing as regular text. Really.<br /><br />It might be useful to do a second entry containing only the text formatting tags, but I also think there may be a need for an exhaustive alphabetical list. Opinions?
