Nope, I havent done that, but I have written letters to people and vented that way, I didnt necessarily pass the letters on to the people concerned, except for my Mum, I gave her her letter, which was quite scary initially, but we talked about issues that I couldnt talk about before!! Not only that, if you're not a very outgoing person it might be kind of hard to have a good moan at 'the person in the chair'. I found that the letter writing thing was good, it took time to do and actually they answered some questions when i re read them - does that make sense??
