Voting starts in March for the Drupal Association Board election.
The last commit was nearly five months ago, and it seems like the last time any of the maintainers said anything re: the D7 version was in February (~8 months ago). Indeed, it seems like May 2012 was the last time any of the maintainers replied to anything in the issue queue.
All of this (especially the last point) raises the question: is this module still supported?
While I myself don't have the time to work on something this big, by the maintainers at least admitting they've moved on, the search for new maintainers can start and this project can continue to live.
Not at all trying to be a dick here -- it seems like some fantastic work has been done so far, albeit for a version of Drupal that's quickly becoming irrelevant.
Alternatively, if this module is in fact still supported and you need another dev to push the D7 version out the door, please feel fee to drop me a line, I'd be happy to help.
