However it has been done in the past. One of the previous elections, when I was Council chair, Reggie kindly allowed me access to the user database. I then correlated the registered email addresses and nicks with a dump of the Garage user DB (provided by dneary/X-Fade).

This list was then given back to Reggie and he did an administrator PM to them, pointing them to Link talk.maemo.org account with maemo.org profile.

Another option is to include it in the TMO welcome emails and/or get new accounts synced automatically - but that assumes a significant portion of future users are yet to exist.
