Am I responsible by arranging an event?
I've put this question on a law site as well but I am always interested in Instructables' answers.
If I arrange an event as informally as I can such as putting a posting on a site saying,
" Is anyone interested in a game of croquet at 3pm at the local park? ; Just turn up if you want to ; at your own risk."
Can I as an ' organiser ' be held responsible for any injuries?
If so, is there a way that everyone can be responsible for themselves?
