Access Google Groups/Docs/Sites using a non-Gmail account
OK, I’ve been recently dealing so many times with the creation of mailing lists (using Google Groups), sharing documents (using Google Docs) and creating collaborative websites (using Google Sites) with groups of people who sometimes do not have (and do not want to have) a gmail account to login to those Google services.
There is a widespread belief that it is mandatory to have a Gmail account in order to acess GDocs, GGroups and GSites, but that is in fact not the case. You can create a Google Id using any email address you wish and never actually create a Gmail account. The link below has some slides that explain how to do that (it’s actually quite simple):
Using Non Google Id With Google Groups.
