With the list, you can pretty much talk about any thing and every thing, really.  For since I've been here (which is quite a while), this is probably the most activity this list has had in a long, long time.
If you're curious about what has gone on beforehand, you can take a look at the webpage where all the posts are stored, http://lists.ou.edu/archives/pwa-l.html
We're usually more laid back than this, but I think having something to focus on (the book drive, mainly) has just made people become more active than usual :)
