As Jeremy says, Data Protection means that the BAA couldn’t do this without getting permission from members. We could potentially have an opt-in members’ directory, but I fear a lot of our members would be very uncomfortable about putting their addresses in the public domain — especially those with very expensive telescopes in their back gardens!
I am keen to develop the BAA website into a more social platform where are members can share images and send messages each other. Perhaps it would be worth giving members the option of specifying a home town that we could plot on a map…
