Can't we use the wiki for this?
Ian mentioned, and something we will have to work out is a way or place for people to submit their photos and stories. We can set up an on line drop (can we use fpaste for that?)
Since we are expecting a large number of replies, a dedicated submission form just for this project will be way more streamlined for both submitters and editors. And as a bonus, we can also roll in validation to help ensure submissions include all the necessary information. There is some software already available, but I haven't found anything F/OSS (but I'm asking around). Even a google docs form would help a ton (but user would be responsible for hosting his / her submission and submitting a URL).
Since we may get swamped with a lot of photos, I would be tempted to not sent it to *all* the lists. However, I would like some more time for submission, so you have a chance to prepare your photo session. Even more if it will include some props (stickers, buttons).
and then send an announcement to all the Red Hat lists, Open Submission for two weeks or 300 photos, which ever come first. Someone with expertise will have to handle the logistics on that. Then those of us listed on the Picture Book wiki ( or any others ), can each choose our favorites, then meet sometime on #fedora-meeting to hash it out.
