This is definitely a very interesting idea and as founder of the Municipal Flag category we want to be part of this. By the way, we do allow more than one location for city flags but discourage more than one log per waymarker per city. The category has been running successfully for two and a half years and I don't think we have more than three or four flags that have been logged at more than one location in the same city.
We are not sure about the restriction of only one log per "organization". We are trying to get as many categories as possible registered in our home town but all we have in town is The Golden Arch, Carl's Jr., Chevron and Travelodge. So, if someone beats us to it we wouldn't be able to register any of the flags in our hometown - doesn't sound fair.
Also, we think that "Organizations" must be defined better. Are we talking non-profit organizations (Boy Scouts, Greenpeace) or business (Ramada Inn, Shell Oil, General Motors)? And what about Sport Teams? This almost justifies three individual categories...
We definitely want to be part of it and want to get it off the ground, but it seems to need a little bit more discussion.
Count us in!
