Hey guys,
I am glad to see all this activity! Sorry I have been out of the loop on
e-mails I have been focusing on our library application for the last
week. I will meet w/ Greg today to discuss project planning for our
pilot.
Let's keep conversations like this on the server-devel mailing list so
we can keep the other people involved w/ the school server aware of our
work.
Please join the Server Developers mailing list here:
http://lists.laptop.org/listinfo/server-devel
It's really crucial that there is good communication w/ the different
implementation teams.
