Well, I'm saying that it should be faster than sending out three or four simple emails, as in you are probably only scheduling with two or three other people. I'd like to literally go to the site and the first page says<p>"Your calendar is already created. Just share this URL with friends. doodle.com/98u89joij"<p>IE, on each new session, a unique id is associated with the session. If I initially input my own availability data, then it saves with the ID to the db. Otherwise, just don't worry about saving anything until someone visits that url and inputs some data to save.<p>Point being, I hoped the workflow would be "visit site. copy url", and you're done unless you want to do more.<p>Edit: for all the other links, being forced to register is sufficient for being too much work.
