Through my visits to POSSE professors over the past couple of days I realized that one thing that is undeniably helpful is a variety of suggestions for open source related assignments. Lucky, that we worked on creating precisely something like that at an NSF-sponsored workshop at Western New England University in Springfield back in May. Clif Kussmaul suggested a project along the lines of 50 Ways to be a FOSSer. So if you're for some inspiration on how to put your students to work in open source communities, check it out: http://xcitegroup.org/softhum/doku.php?id=f:50ways

And make sure to send suggestions to the TOS mailing list!
