ideally, every week would be the best, tho the main issue is if we can get someone to host them that frequently...
i quite liked the 20:00 gmt on saturday, and it seemed to work for most people. tho maybe alternating times every other week would be best - one earlier, and one later.
i do very much like the idea of it being a regularly scheduled thing, tho we need a minimum number of participants... maybe if more than say 4 dont join, it would be canceled for that week.
