currently I am in one group / pack and if I had been in this position back when I was 12-13, around when FH first launched, i'd probably get into several groups and be able to maintain contact in each of them, tbh. now though... I'd probably only handle just the one, since I'm too busy IRL and my mental health state often times leaves me bedridden or unable to communicate with people properly for days, so I kind of disappear and come back when I feel better so I'm not a sad, heavy burden to everyone else in the group!
so... yeah, one, I guess. but I guess I could do two, but only if there are, like, under 10 people in each, otherwise that's just too much for me.
