Dear Alain.
Yes, it is wiki. But maybe it should be on Trac instead, as Marcus suggested, so the content be in a single place, and the trac roadmaps
I have not really suggested to use this or that. I just wantet to make clear that we should keep the content in one single place for better maintainance.
There are some disadvantages in using trac which I have already lined out. One is the 'bad url' to access the trac pages. If artwork.centos.org (or something like that) would link to trac and the wiki just points there, all content could be kept in the trac wiki.
Best Regards Marcus
