Canadian Geographic Photo Club

Canadian Geographic has launched an online Photo Club - CG Photo Club.
You can view galleries of the growing number of members. Getting a free membership will allow you to create your own gallery and post comments against other member's photos. You can subscribe to any of the member's galleries through RSS or Atom feeds.
There are a few forums as well, which as of today do not have a lot of articles, but this may change.
There is also a section called Ask CG where you can ask Canadian Geographic a question. The first entry asks the question 'What goes into choosing and designing a cover?' Have a look at the article and visit the site.
