Here's what I do:

1. Everyday I log in to David Allen Company forums and click the "What's New in the Forums?" tab.

2. I browse a list of all threads that were updated from my last visit and open each interesting topic in new browser tab (threads that contain my own posts have a special icon with a white arrow on a green circle).

3. I browse/read new posts in each tab, post my comments and close the tab - done!

4. When all David Allen Company forums tabs are closed I log out.

I see no reason to keep anything open when I sleep!

I always close the windows to stop the flies from getting in...
