I noticed your contribution this morning to Nice Guy and saw that you were having problems with links -- specifically, you were trying to include links in TV Tropes-style markup. As you noticed that doesn't work here, because we use MediaWiki and not PMWiki. I've corrected your example, so if you want to go back and look at it you'll see how the markup works. You might also want to look at our So You're a TV Tropes Refugee page, particularly the Editing Quick Start section.
