Yeah, perhaps only send the notice via the same mechanism used to send the ballots (which incidentally I never got).
But I'm talking only in the instance where the balance is quite heavily skewed one way or the other...

I don't think we should have a "hard & fast" rule that if you're mod or super mod you can't participate, but I do think we should strive to have most such mods hand over their privileges for the term of their office*. Unless said privileges would be genuinely needed by those in office to carry out their duties "effectively". I think there should always be at least one or two top-tier mods who keep their status regardless of whether they're serving or not, just as a insurance mechanism against any new mods who end-up causing mayhem rather than harmony.

*Will that mean they get those privileges back again once done, & those that took their place also keep theirs?
Not sure. I guess having more & more mods over time can't be a BAD thing, can it?
