can this work with 3.7 ?

You cannot install this on 3.7 unless you edit the xml, but I see no reason it wouldnt work.

thanks for reply I still using 3.6.8 but when vb 3.7 gold is out want to make sure all hacks in my board will work .
thanks

I have upgraded to 3.7 and this still works fine AFAIK.

This is a great idea, something that should be vB standard. Thanks for posting this hack it has just made my life so much easier, now to wait for the hourly update cron job to happen to actually see how many inactive users I actually have.

Yes, it is an excellent hack. It changed my usergroup numbers quite dramatically. Not sure how I missed it before now.

Future Addition that would be nice: Have multiple usergroup demotion/promotion options.

is there any way to make it send emails to inactive users?

Nope.

how to run the move operation manually?

thanks !!!!!
