mh, poll sounds good in theory, but who is gonna see that in the first place? Imo the important thing would be if we agree on a date we keep going for a while (monthly is too rarely imo). So even if we're only 10 the first time keep at it and it the word may spread, wohoo.
Or alternatively we try to advertise as big event and get as many people as possible for one event and take it from there. We'd need people with lots of connections to old players, though (me not lol). Could be disappointing, but so what ;)
