I like the idea of a blog. I don't know if you have a favourite blog site / software already, but I highly recommend WordPress (
http://www.wordpress.com/) It's free, you can have multiple accounts for one blog (i.e. you can have multiple authors who are allowed to post or contribute), and you get 3 gigabytes of file storage (that’s about 2,500 pictures) with a free account. Also they have really good "hit tracking" stats, which would help if we're trying to generate media interest (we can tell them how many hit the blog gets per day/week/month/etc.)
