I'm slightly surprised that 'new' posters feel they have the right to complain about a poster's style. I would have thought it was common sense, and considerate behaviour, to lurk for a while to get the feel of a forum before posting, let alone complaining 
I have reported one or two posts that I thought contained personal insults, in line with GNHQ's advice to do this rather than inflame things further on a thread on which feelings were already running high. I also report any obvious advertising - I'm sure none of us want the forum clogged up with adverts for the latest snake-oil and what-have-you.
jo8 what can I say? I too felt the sharp edge of your tongue on occasions when I first joined, but I consoled myself with your own words that 'it's only an Internet forum'. I also quickly realised that you don't aim your barbs at particular people and most importantly, there is never any malice in your posts, you are simply saying what you think, and probably what a lot of others are thinking too, but don't have the courage to post. Gransnet would be poorer without you.
So I hope you are feeling better now 
Hope you're all reading this GNHQ!!
