With my suspension on Area 51 ending in 21 hrs, I have a feature request for a suspension queue. A suspension queue would permit any suspended users to queue up their contributions to be committed when their suspension is lifted.
I think this would greatly eliminate the need for sock puppeting and other devious tactics people other than myself oftentimes stoop to. Those of us who are suspended but have good ideas could use this new functionality to make sure they get committed once the suspensions end. This feature will also help mitigate the damage that suspensions have on good contributions.
