Hi folks. I'd like to get some insight into which features are being used and how. Everyone uses AO a little differently, I suspect, and I'm curious of what we appreciate and why.

Please note, this is *not* a bitch thread, to complain about things or wish for changes and ask for features. You can do that elsewhere. Simply put, I'd like to know what you currently use, and why or how it makes your experience at AO better/easier/less agravating.

--EDIT--

I chose the following:
-Private Messages (or PM's)
-AntiPoint system
-Index/portal customization (main page display)
