Thanks Erimus for posting that info. On the internet you don't know who you are dealing with so you have to be careful and I was a bit concerned so that's why I posted my final comment on here.
It's a shame, because people like that can spoil it for the vast majority of genuine people who follow this forum and post on it.
From experience in litigation I can only suggest that each incident is recorded with the date, time, place etc in fine detail just in case the matter is taken further.
