WE Notes
WEnotes is a bit of an experiment at this stage, and isn't really ready for widespread adoption. As an alternative, I would recommend using identi.ca alone. That has the advantage that you start with a clearly defined Creative Commons license on all of the posts. There is a Widget that you can use on a page to bring in all of the identi.ca activity for a particular tag. There is an example on the OERu page.
Another alternative is the LiquidThreads feature that is built in to WikiEducator. The discussion page of every page allows threaded replies... which may be helpful in following the chain of message and responses in a group that is working asynchronously. Users have the option of having new messages mailed to them (by setting the LQTemail option on the Gadgets page of their preferences.
