This has gotta be like the glitchiest feature on the forum.
When I was making my Tim Burton thread, of course I wanted to be awesome and post the trailer too, so I wrote it in the usual manner (using the link from the "Share" tab on Youtube, as I'm supposed to).
[youtube]link[/youtube]
It would preview fine, with the video visible and playable... but every time I posted the link, I'd find the forum automatically wrapped it in needless code as so
[youtube][url=link]link[/url][/youtube]
When modifying it back to a playable state, as soon as I hit save, it rewraps the link in the redundant code, which breaks the Youtube tag.
My Death Battle thread wasn't that long ago, so something seems to have changed in the last month or so.
This thread is half "cry for help" and half "the more you know".
