Thanks for the clarification. By all means please set a date for the end
of the Redmine test. Note, the only reason we are trying Redmine is

repos, one per plugin which would easily take care of the permission issues.

I would like to hold off on setting up trac/svn for plugin-dev until we
are sure that Redmine/git is not what we want or doesn't work the way we
