Please review, and especially add new tasks to it.  I'd like to see a
variety of tasks, at different skill levels, including tasks for
various functional areas. I'd recommend following the model I've
started, listing the skills needed and the skills gained.  That will
help make volunteers more easily find something that would be
interesting for them to work on.

Let the fun begin!

Regards,
