I think they have a registration system which works kind of like Outlook does inside an organization but for everybody. That way you can schedule something without the email chain of "I'm available on Tuesday afternoons", "I'm not but how is Wednesday", "I could do any time on Wednesday except for 11:00", "How about 10:00", "That works", "Wait, did you mean 10:00 UK or western Europe time", "UK", "Sorry I'm an hour ahead so that's the 11:00 I couldn't make", etc. I don't know if they do anything else though.
