Sticky Logins in RAFINO.ORG

Lately, our website has been dropping logins after 20 minutes of inactivity.  The scenario is trhis:

(1) You log in and do some things

(2)  You do something else that distracts you from our website and when you come back after 20 minutes or so, you are forced to log in again.

We have finally gotten through to our internet service provider and gotten them to extend the "lifetime" of all our logins.  Your login should be able to stay "alive" for the better part of a day now.
