We have been waiting for someone to do it for _too_ long.  Please feel
free to submit something. I recommend you get the list of changes from
the archinves that we agreed to for /contrib and use that as a guide.

I am still waiting for all valid gborg projects to be moved to pgfoundry.
How many years has that been in the air?

I know people have said they would complete these items, but they have
had sufficient time, and it is time to bring in other people for the job.

Our web site is looking great and is well organized.  It is time for us
to do the same for add-on projects.
