In the discussion at the hackfest (following the irc discussion) we
felt that using trac would be a lower threshold to cross - a number of
us know it (as admins), as do the users. Personally I'm not averse to
using redmin so playing around on a test instance would be nice) but I
think we should set some kind of cut off date and make a decision -
Paolo and others are getting frustrated trying to manage plugin issues
so it would be nice to get something in place as soon as possible.

Ok I think Pirmin broke it down better than I in his follow up post,
but lets try to separate discussion about the management of the
codebase for the qgis-django project which among other things will
provide the new plugin portal, from the plugins themselves. In the
case of qgis-django portal, the suggestion was to completely manage it
using github infrastructure.

Yes the idea was that each plugin author would be given a folder that
only they (or team members) could write to. Its an admin overhead (for
you?) but would be the idea - liberal access so that anyone can have
an svn write account but they can only write to their own dir.
