Gransnet has hundreds of members and many more than three who post very regularly. Far too many to be cliquey. Of course there will be one or two members who one finds irritating, but that's life, it is no different to ordinary everyday offline life and even then one cannot always cut these people out of one's life.
I have been on Gransnet almost from inception. I have had the occasional clash but mainly I have found GN members kind, compassionate, and witty. of course there is the occasional spat, but again, that is life.
Personally, I only very vaguely recognise the name of the OP and I have no memory at all of which threads she posted on so have no idea which threads caused her so much upset. If I find I do not like the tone of a thread, I just leave it alone and move on to a more congenial one.
I am sad that a member is leaving the forum feeling so bitter and hope that one member's unhappiness will not stop others jpining what is a generally a happy and supportive forum.
