Avi, I have been trying out a bunch of things with the site (see posts here
http://openanthcoop.net/forum/index.php/topic,9.0.html )
There are three main things we need to sort out:
1. Setting up a seminar doesn't do much at the moment.
2. in posts, you cannot seem to link to other webpages -- or perhaps I havent seen how.
3. most article length files are 'too large' to attach to a post at the moment.
From messing around I find that the general usability of the site for typical OAC purposes is very good, the ability to modify messages for example.
