This is another of Caroline's starting points, and next above is my first addition to it.
Proposed rules: Well, I don't think there should be many rules.
1 I think there should be a good leeway for freedom of expression, but those running the blog have final veto of anything that seems purposefully offensive, obnoxious or obstructive. You know the sort of thing I mean!
2 Each collaboration should perhaps have a running list underneath of the people that have added to it, starting obviously with the originator.
3 Not sure about this one, but I think if you intend to work on any doodle, you should try to pick up the latest version of it. Otherwise there will be too many myriad versions knocking around. I think it will be more interesting to have focused cumulations. ?
4 As Caroline says, if a person wants to contribute they can leave a comment with location of picture version, or new picture. I guess blog membership shouldn't be too large, otherwise complete bedlam, but on the other hand, with more people running it, more will happen more often! Maybe just see how it goes, how popular it is and so on. Thoughts Caroline?
5 Editors of the blog can decide when a doodle has done the rounds enough, and call it closed. Best stages of all these exchanges could then be plucked from the archives and put in best of archives. Something to consider a bit later on - I want to put my own house in order (Elbowroom blog) before I get entangled in that!
6 What about the camel logo? Did you have some idea of using that Caroline? Or we could just integrate with the blog title.
