I think it would be a good idea (don't think it exists now) to be able to label forum members as Active (and particularly Inactive).
We've lots of members but are at pains to get more members active and I thought this might be a bit of an incentive.

Hello PinkSapphire,
There isn't an actual system that labels people as "Active", but there is a modification "Inactive Member Reminder" that you can set to e-mail members after X amount of days without visiting the forum. (You can find this in the Mod Center)

Thanks Subliminal. Yes we do use that feature and like it.
