with most of what everyone else has had to say but particularly at this time with Tara and Wyn. I think we have to use sound judgement and think about what we are going to say and to whom we are saying it. Especially if that person is vulnerable. And, if we don't know anything about the subject then don't say anything.
For myself, I find that it is the common background which is helpful. We can tell each other things that other people wouldn't understand. That is great for me. I don't agree with everything I read on this site and that is also great because it means we have freedom of expression and no one is going to 'disfellowship' us for speaking out of turn.
I think that we probably all have a different idea of what support is. I like it when people offer me constructive criticism. As Briannon said, that is how we learn. However if that same advice is offered by a person in a put down or superior, attitude, I don't like that at all!!!
