In the Evernote Forums, a user posted about a shared notebook he created for his camera model. Other users could contribute to it, and it became an awesome resource for anyone using that particular camera.
I wanted to do the same thing for Canon 7D users.
The link below will take you to the public Evernote notebook. You’ll have read-only access to any information that gets dropped in there. If you’d like to contribute, shoot me a message via the contact form on this website, and I’ll add you to the notebook with edit access. Have friends that also use a 7D? Pass along the information to them, as well.
