Well if everyone likes it and Marko's good with it then we can go ahead I guess.

However, this test one I set up (and invited JJ and TT) to put markers onto will have to be scrapped as I'm the owner of it as far as Google is concerned. It would obviously be best for marko to be the owner so he'll have to set it up.
That's easy to do anyhow but it's a manual invite system so I guess we'd have to ask him to invite us and provide our email addresses so that he can. After the initial novelty wears off it should only be work for Marko as new people join and ask to be able to place a marker.
