Sorry to rehash things if the moment has gone.
I'm not sure if I'd be considered a regular or a drifter. I read a lot of threads but a lot of the time I won't contribute if it's turning debate-y. I am personally not interested in debating with people as it makes me anxious so I tend to leave those threads alone as I want my time on BH to be fun not stressful. Sometimes I write responses then delete them. I can be a bit sensitive so something might upset me for some time (eg if I got 'attacked' for something I said or even just a particularly negative comment) so it's better for my wellbeing just to read rather than put myself out there and contribute sometimes
