Ok, so sometimes I keep frequently accessed sites as icons on my screen so I can go there with one click.
I'm probably not the only one.
Every one of these sites requires its own password to access, and after learning the hard way that having the same password for everything was a bad thing... it became problematic to remember which password went with which site.

Every site seems to have its own default setting as to when they check to make sure that their members are active by closing access and making users run the whole prove-you're-you gamut. That's not a bad thing... just an annoyance, but...
...I suck at remembering passwords... and other things... that's just not what I do.

There might be others like me.

So, I think that a timely beforehand prompt might be in order alerting a user that their allotted logged-on time is about to expire, so that a reset of this arbitrary default clock can be re-extended without interruption while they still know that you are in fact you.
