Thanks for doing this, FF.
Please add the DC Chapter ping list managed by BillF and Angelwood.
DC Chapter ping list is for those in DC area who like to participate in some of our considerable number of FReeps and other actions, AS WELL AS FReepers located anywhere who like to read of various DC Chapter events and FReeps.
Have you thought of making a ping list of those who keep ping lists? Call it the "ping ping list?" Could be used to update the info if you do this again.
I am hoping to visit the DC area in March.
