Are there any plans for it to work with secondary user groups?

Nope.

what are most of you setting as defaults?

Thanks! :D

This is going to help me as I choose to have my 'inactive' group setup with this mod and then the 'mass pm' sent to these folks to prompt them to participate or at least visit the site and hope to get a few clicks on ads ;)

Ran last night and identified my inactive users! Worked as advertised! ;)

Thanks Paul! :D

installed thanks :)

I have set up which groups to check for inactive users, and a new group to move inactive users to. I clicked on the hourly update cron job and it doesnt seem to have done anything. No members have been moved. Any idea what's wrong?

As the text says ;

Paul,

Thanks for the reply, much appreciated. I waiting for the daily update cron job to run, which was set for 20:00 tonight. Nothing appears to have happened; no inactive members have been moved to the specified Group!

In the Cron job, it says the File is ./includes/cron/inactiveusers.php. Is this correct?

No idea what that is, but its nothing to do with this mod. This does not have an associated cron of its own - like I said above, it taps into the standard daily update cron.
