Man, one of these days I will simply loose myself in all these Google services. I used to be a simple happy GMail user (despite that some people don't think it is that great – I would not no as much, so should I really care?).
Well, no, I just could not resist, I had to try GMail for your domain thing. Calendar and Talk were added to it by default. I now have enabled Sites, Web Pages, Start Page and Docs. Will I use them all? I don't yet know....
