Members used to log in here to change their delivery options - digest or not, vacation hold, that sort of thing. The list no longer sends anything, so there is very little left to set, but the login still opens the options page for the handful of addresses still subscribed.
Lost the options password? It was mailed monthly and the mailings have stopped, so there is no self-service reset left. Write to ivo@rawsocket.cloud if you want your address removed from the subscriber file; the archive pages themselves need no login and never did.
