Thanks to everyone who posted with votes of confidence. My faith has been restored and I'm not going to leave - will reset cookie at some point. I don't have regular access to a computer at the moment.
Of course I realise that people like this unwelcome guest are going to turn up on an open site - just like in the real world, and I should ignore his/her comments. Was annoyed when I originally posted, but now couldn't really care less what this person thinks. Obviously a deeply sad individual with a lot of spare time on his/her hands.
Part of my MA involved interviewing folk musicians and singers about their thoughts on the revival and the contemporary folk scene, and one of them spoke of his love for the people on the folk scene and the way they interact, suggesting that a sense of 'folk camaraderie' exists. Despite occasional idiots trying to spoil things, from my experience of festivals, sessions, clubs and Mudcat, there is certainly rings true for me as well.
Re: getting my MA online - this something I will endevaour to sort out after Xmas
