I was just asked what "Supporting Member" under my user name meant. So, I thought I'd make the answer public in case others were wondering same. I pay a small annual membership fee to AOD. Doing so gains you a few modest performance enhancements, such as a larger PM mailbox capacity, etc. AOD seems a worthy cause to support, and I figure it's only fair to "pay to play".
To do so; click on "Settings" in the tool bar at top of screen; then click on "Paid Subscriptions" toward the bottom of the side bar on the left side under "My Account".
Happy new year to everybody.
