Do you need a google account in order to view/edit a document in google docs?

I'm trying to start a little collaborative document group and I would like to use google docs. However not everyone in the group has a google account. Do they need on to use google docs (to edit or view the files)? Thanks.|||http://docs.google.com/support/bin/topic鈥?/a>|||Yes. You need a google account to do anything with google's extra services. If you have a gmail email account, that is a google account that can be used to sign into things like google docs.
