While trying to link an IRC channel on a tag wiki, I had to realize that all four ways to create a link in SO's markdown failed. Trying a bit around, I noticed the link would render if I would change the schema from irc to http. It seems https and ftp are working as well. But what else does?

The official documentation doesn't mention which schemata are actually supported. Here on meta, I can only find answers regarding unsupported schemata. Am I missing something?

  • Oh splendid. My first question on the SE network ever and I genuinely made a fool out of me. Dec 14, 2013 at 15:13
  • You absolutely haven't. Don't worry about it – this is just Meta.
