Yes BNP could be a problem. I'll think on that. As long as it remains practical I'll cast a quick eye over all edits anyway. Edits are logged with email and IP address so I have some chance of kicking the culprits off.

A possibility is that the event has up to 4 joint owners one of whom must approve any edits. Whoever first posts the event becomes the owner and must also approve additional co-owners. (Does that make sense?) More complicated but could be made to work.

Just to be clear on the artists thing - that's actually two lines (not 3, my mistake) and it's lines in the actual listing, not three entries in the box on the form. You can get quite a lot of artists in the space, see some of the festival listings. The limit should only be an issue to festivals. Most people won't get close to it.
