I agree - I posted a note to the moderator's last night offering to help people get adjusted to the new board, kind of like a cheat sheet of where things are on the new board. I think that for some it's a huge change versus a small change to others - for people that are not computer savvy I think it created a feeling of being lost and confused.
As for people leaving to go to other boards I checked a lot of boards out before I came here, I'd interact and ask questions and no one answered me. Here I feel like everyone's kind of like my extended family that I look forward to talking to each day. If some leave I think we will see them come back because there's not much out there.
