Dear all,
After the (minimal 
) feedback on what the best tracker system would be for the project, I suggest to request a trac instance to be set up on the osgeo infrastructure.
It will also provide us a WIKI that can be used for the development process in an interactive manner.
We will stick to the Plone based community website for the product related content focussed on the users of the software. The trac site would be focussing on development strictly.
If no objections are received by Monday, I'll proceed with the request.
A sample can be found here: MapGuide Open Source

Ciao,
Jeroen
