Thank you 37signals!
Even before I signed up for my Backpack account, I had been wanting to allow others to comment on some of my todo items on pages that I was sharing. I use my BackPack account as my personal intranet. And I have a page for each of my major topics and some just random bits of information. Most of my projects involve doing some side programming for websites. In order to keep myself organized, I’d like to allow others to view the pages, add todo items or post comments on the items, notes, files that I already have up there. Up until now, it has been rather difficult to do.
