A Youtube Button? What other sites are supported?

[Hack&Lube]

The "other" forum has added a youtube button to their VB code beside the insert picture button. I don't want to encourage Youtube spam but I think forum members have shown proper restraint so far as most know about the youtube /youtube tags already. This would just make it easier to post something and reduce the amount of youtube posts in the test forum.

Also, many people don't know this but other embedded videos from other sites are supported. Is there a list of the supported sites and requisite tags that could be posted up? I know that nhlvideo /nhlvideo works (add brackets of course).

Those are the only two I've added so far, but I think there's a plugin to add a ton of them. And I think a button in the editor would be fine too.
