Basically, the way I envision it is that on that page it will check to see if the cookie that keeps you logged in is set in this browser. If not, it allows you to click a button to have it set it. If it is, it says so and lets you know that you can remove it by removing the login key in the list below it.
It might also be beneificial to somehow highlight the key that is set for the current browser/IP address (however that is handled) in the list so the user knows which one to remove or keep.
This basically keeps me from having to log out right away and log back in and remember to check the box. I sometimes move through the form too quickly and miss the box multiple times in a row.
Thoughts?
