Looks like there were the minimum 4 APers doing the Green course last Sunday at Lock 7, so you did get ranking points from Attackpoint. They didn't show up immediately after the splits were posted as it takes 24 hours for the site to notice new races and do calculations. Ken (site designer) is a genius!
I added you to the Attackpoint "group" for EMPO. You can always take yourself off, but there's not much chatter there. However, you can post discussions that are seen just by the other "group" members (currently about 14 people). The group should show up in the lower right of your screen (on a standard computer, not necessarily on mobile). WCOC also has an AP group, but I haven't seen any posts there in months.
