Alaska Snow Conditions website

This will be a simple website, which will allow users to enter information from around Alaska detailing snow conditions and riding conditions for skiing and snowmobiling. Ideally I would like users to be able to create an account and login in, from they're they can choose which area of the state they have visited lately and enter information about snow conditions these areas would ideally be linked to the forum page that they were interested in. Also I would like a forum for users to use like the one found on [login to view URL] . Which the site administrator would manage as far as the topics of discussion. I would also like the site to have advertising space, also as part of the user account feature I would like them to be able to load photos onto a photo gallery page which they can tag which area of the state the photos are from.
