Thanks Paul for the welcome and the advice for getting a MapGuide
install setup for testing. I'm really looking forward to contributing to
the project. I was on the site looking for guidelines and didn't find
anything. You do have some pages up but there is not content yet. Does
anyone have any recommendations or best practices that I should be aware
of? I just want to make sure that I meet any standards that have been
set and that my contributions are received well. Thanks.

Hi Tim,
Welcome to the project. If your interested you can also download a live
cd of MapGuide Open source. (http://mapguide.osgeo.org/node/127) and run
it in vmware. If your interested. It's a nice way to see how fusion
works with both platforms and it will help to make sure that when you
fix an issue on one platform that it doesn't expose an issue on the
other so it's a good idea to have setup anyhow.
Cheers

Paul,
Excellent! Thank you very much. I've making some good head way
on the
whole Legend issue, especially when using multiple maps within a
map
group. I'm going to switch over to a single map in the map group
and see
what results I get also. I'm happy to be able to submit changes
to the
MapServer side of the project. I hope that my work will help
others that
are already using MapServer adopt Fusion as their framework of
choice.

Hi Tim,
the project is not dead but I don't know how many folks are
using it
right now. I know that MapGuide is actively using it and the
Autodesk
team there is actively finding and fixing bugs related to the
MapGuide
support. DM Solutions is also actively using and developing the
framework and the MapServer support.
I have added you as a committer, welcome aboard!
Cheers
Paul
