OT: best solutions for tracking projects and skills needed

I realize this is off-topic, but I’m not sure what forum is best for
asking
about this. I figure that at least a few of you are involved in civic
hacking groups.

I recently joined a group that does civic hacking. (Adopt-A-Hydrant is
an
example of civic hacking.)

We need a solution for tracking projects and the skills needed for the
projects (such as Ruby on Rails, Python, Drupal, Javascript, etc.).

I’d like to hear from those of you in similar groups that have a great
system for tracking projects. Is there an in-house solution you use, or
is
there something else available?
