If I open a thread out of idle curiosity rather than interest I am quite happy to just leave it alone unless there is something I can contribute, with positive effect, and that hasn't already been posted. For those threads where I have an interest I'm happy to participate where the discussion is rational; where it is (IMO) emotional I can leave the thread alone with ease and no frustration at all. I have limited time (and limited experience in such matters) so I'll only PM someone if I regard my comments as having limited application (and thus not worth the public attention of the thread) and think my contact will be well received.

I can't recall anything written by this thread's contributors with which I could take serious issue but I've noticed some other members seem to have 'history' in their relationships with others. I learned long ago that debate rarely changed anyone's opinion. More's the pity, sometimes.

Cheers, Rowan
