Like so many Web 2.0 toys I like the idea of Tungle.
But I doubt I’d ever have the need to use it. I don’t have to organise quite so many meetings outside of work. And at work we use Meeting Maker.

I think that if you don’t want to bother with downloading and installing tungle you can use ScheduleOnce because there’s no registration.
You can also use TimeBridge, you need to register to organize meetings but your attendees needn’t, and you can also connect it to your outlook or google calendar.
If you don’t want to conect your calendar then you don’t need to install anything.
However, if you do connect your calendar you can also create a free availability page where other people can see when you are busy and when you are available.
