http://project2.wikimedia.org/ is a Redmine instance
with a data that
was migrated from
bugzilla.wikimedia.org
The data is a few months old, I didn't get around to updating it
recently. You will have to use the "forgot password" option on your
bugzilla username or create a new one. Also it does not receive emails yet.
This instance was setup for initial evaluation and has not been
rigorously tested, so let me know if somethign is badly broken.
