Two updates to the site today.
First, now you can embed YouTube videos practically anywhere. Just paste the YouTube URL (http://www.youtube.com/watch?v=2Op3QLzMgSY) and it will automatically turn into the proper embed code in your post. This works in homework assignments, homework comments, forum topics and replies. This applies to class creators also, and videos can be embedded anywhere in the class lesson and assignment content. For example, I’m working now to embed the video lectures for SICP into the class itself:
http://curiousreef.com/class/structure-and-interpretation-of-comp/lesson/1/
It should make the classes more convenient to use since it will all be on the page for you.
Lastly, all links now have the nofollow attribute attached to them. This tells search engines not to follow those links, which means they get no SEO value from them. The reason for this is to try to deter spammers. There have been repeated attempts by spammers to post links in the forum, and I hope this measure will help get rid of that problem a bit.
