Whenisgood.net: Easy way to find out when everyone is free

I just found this site and thought I would share. Ive been looking for something like this for a long time.

You should check out http://tungle.me, it's a much more complete product (calendar syncing, nicer UI)

http://doodle.com is yet another competitor.

Doodle is in fairly widespread use at my school

I don't know. How "complete" do you need a one-off solution like this?

I'd have no qualms sending my friends or a work group to this site to solve a scheduling problem in a hurry.

There are lots of competitors in this space: http://timetomeet.info, http://www.needtomeet.com, http://www.convoko.com, plus the ones already mentioned.

The "meeting times" apps are becoming as numerous as project management apps and URL shorteners.

Doodle is great, used it to organise an office LAN party recently. No reg, no hassle - just works, highly recommended.
