This is exactly the feature needed here.
No, that's not right. As it says, users get added/removed from groups after reaching designated user-data milestones. Those min/max values refer to post counts, or # of warnings, or how many days they've been a registered. There is no type of "expiration date" setting on group membership possible with auto groups.
What the OP of this topic wants is something that will expire exactly 1 year after the moment they add somebody to a group.
Auto Groups is not a subscription program for phpBB. The OP is right to request such an extension as there has not been one created yet for phpBB 3.1.
