Redmine

Thanks for Redmine. It is working well for me. A feature I would like to see added is the ability of an existing user,
with proper role, to invite others to join a project.

Example:
JoeUser with Role Manager invites bob@example.com to join project XYZ.
An email is sent to bob@example.com with some default text (or a special message written by JoeUser) and a URL that
will allow him to register and automatically make him a member of project XYZ.
If bob@example.com doesn't register in N days, the url is removed.

Thanks again.
