Walpha Wiki
This wiki will be tracking how Walpha might be used by students and as a tool in outside the classroom. As stated in the wiki:

A few of us interested in exploring the implications of Walpha on secondary and undergraduate mathematics education thought it might be useful to have a wiki where math educators could contribute documentation regarding Walpha's use in such teaching contexts. In particular, we're interested in documenting how Walpha can handle or help with handling common problems asked of students in these courses, as well as how Walpha might be used as an instructional tool when teaching students about related content.

It will be interesting to watch this wiki as it changes.
