  I agree that it's probably a good idea to send out a message to adoptersit's not just the potential adoptees who might need a 'wake-up call.' The message that you have provided looks pretty good, too, but you probably ought to include a link to the project and the talk page, just for convenience. Unfortunately, I don't use AWB (although I probably ought to request permission to use it; I just never got around to it), but you should be able to post a request on WP:BOTREQ for someone to send this message to everyone.  Regarding the template I made: I am pretty sure it's not possible to have it automatically order people by date who already have the template on their pages, which is why we have bots that go around adding the dates to maintenance templates. We could do it by hand in perhaps an hour or two, though. If you think that it'd be useful, I wouldn't mind doing it over the next few hours/days. Any people who subst the new dated template, though, will be taken care of automatically.
