Hi all, A friend of mine has shared his calendar with me which would help me out lots knowing what's going on at his restaurant. Problem is, he is mac everything, and I'm not (not that I have anything against them). He shared his calendar with me which I received an e-mail to join his calendar. When I click on it, it's asking for an iCloud login. I've tried for the past half hour to create one, but to no avail. I now have an apple ID and have installed the iCloud on my windows machine, but it's giving me an error - This Apple ID is valid but is not an iCloud account. How can I create an iCloud account so I can view this calendar?
