The way it is done now is a bit of a hack. So there are problems with it - like it won't show up in the preview.
When you are writing a post, put in "{ embed }xxxxxxxxxx{ /embed }" (without the space or the quotes). Replace "xxxxxxxxxx" with the goofy youtube number. Something like gDd-EYbXNqU - when you are viewing a video, the goofy youtube number usually appears right after "v=". Sometimes there is a "&" so the goofy youtube number ends just before the "&".
has something changed? i embedded as such under arts group,but it shows a big blank flash object. like this edit: oops. hm, no that did work fine. maybe it's just My 2 videos that are screwy
ahhhh ok, i see now.. only 1 can be added per post
