Temporary Usergroup change for all members

[sierra513]

Hi,

First off... let me thank everyone here for all the great info and mods that are available! Its been invaluable to me, a rookie!

I have premium level memberships available at my site. I would like to do some 'Free Weekends' to allow members to play with the premium pkg features. My site is new and small...but I would like to be able to do this on a regular basis.

What I am looking for is, a way to change all members that are in a specific usergroup, to another specific usergroup for a specific amt of time. (could be hours or days) At the end of that time period, I would want them all to return to their original usergroup. Is that possible? They may come from multiple original groups, so being returned to where they started is important.

I have looked and havent seen anything that would do this. If there is something out there that would, if someone could please point me to it, I would appreciate it.

Thanks in advance.
Sierra
