also, how do I embed youtube vids?
you can't yet
but there's an open issue about this on github
https://github.com/wetfish/online/issues/41
once justin puts an example schema in the repo I'll be able to add that feature
Will it be for all video sources, or just youtube?
I like newgrounds more, so.
It would probably work the same way as the wetfish wiki. You can embed from specific sites like YouTube and Vimeo and you can do HTML5 video as well (webm, mp4, etc)
I don't really consider flash animations to be "videos", most don't even work on my computer. Does Newgrounds even have an embed feature?
