Hmmm. I fit the newcomer category and like Hebredean and others, lurked for a while before feeling confident enough to post. I'm very careful about sharing information on line, I'm a member of a couple of groups, both private and related to hobbies.
This thread is beginning to reflect the combative/confrontational approach taken by a small number of people on gransnet.
JessM said a poster drove 'many people' mad, she didn't say she was speaking for everyone, Sel.
Anniebach, so far as I am aware, there are no set 'group norms'. There are guidelines. That's the thing with groups, they form, norm and storm, especially when new people arrive, and regular group members move on or leave.
It's up to each of us as individuals how much we join in, how much offence we take and how we behave on line. My experience of groups is they can be great places to be, but they can also scapegoat, bully and cause emotional harm to folks. That's why I'm ok with the moderators keeping a watchful eye.
