Jump.com: "We are no longer accepting new registrations to the Jump Beta. Please check out MSN Calendar to sign up for this new online calendar service..." I was excited to see the snazzy new DHTML-enabled interface Microsoft surely put on their new calendar for IE5 users. Alas, it is but clunky ol' HTML, which makes using a web-calendar a pain. Nor does there seem to be any Outlook integration. But it has a nice help interface.
