pasting a youtube video link embeds it it you use http:// but not with https:// which is very annoying as youtube runs in https:// for me. I'm lucky that i tried to edit it last time i posted a youtube link, the previous time i didn't and just left it as a hyperlink as i though i was using the wrong button in your forum software.
btw, you can also vote your own threads in these forums 5 stars! Please fix this too! I voted this thread 5 stars to prove my point
