sundays afternoon could be an option for me, but would probably mean morning or even earlier for some of you. Sunday evenings... Well, could be possible, but frankly that would mean shorter sessions as I can't afford to stay up too late on a sunday night. We usually stop session around 2am my time, so on sunday night, might end up around 1am instead.
Friday evening would allow me to stay around the same time, but if some of you work around that time, might not be an option either way.
When are you starting on those hours, nevri ?
