[Glade-users] Abusing Glade? :-)

[Tim Cook]

Hi Tristan,

I got so excited with your answer that I immediately put people to work
and started a development plan. :-)  https://launchpad.net/cdd as part
of our umbrella project https://launchpad.net/mlhim Hence I forgot to
send a BIG thank you for your reply.

If anyone is interested in learning about leading edge healthcare
information systems and would like to join in the project, the current
primary mailing list is actually the OSHIP developers list
https://launchpad.net/~oship-dev since it is the oldest project.
However, we will be centralizing on the MLHIM umbrella soon.

Cheers,
Tim
