I have established the three tier hierarchy for this project now.
At the lowest level you have the individual postings themselves. At this point in time I have written 4 (Turimetta, Mona Vale, North Narrabeen pool & Forresters Beach)
These role up through a State Level site (in this case it's this site... Australia-NSW).
The states role up to a Country Level site (here's the link to the Australian site)
And the Australian site allows you to navigate up the global site http://freephotoguides.blogspot.com
I have started spreading word of this project in a limited manner to see if I can get some other photographers to start writing guides for it. I would like to hammer out all the kinks before taking the project out to the wider world.
