Time to stay logged in

[#1]

Peter,
Believe you should be able to set this period when you log in - there's a field for minutes to stay logged in.

Quote from: Peter

or should I just be looking to add community.plus.net cookies to the exclusion list for cache clearing on those workstations I use to access the site?

This would be the way I would go about your situation Peter. Im not aware of any way of implementing an idle timeout easily from PlusNets side.
