I got all excited last week about the prospect of using Doodle.
Having now set about using it to arrange a national meeting I've rather gone off it - for speed I just used a standard email instead.
One thing I really didn't like: the way that you have to specify each possible start time - if all day is available for a meeting then that might require participants to click on 8 times just for that day.
Tungle looks a lot lot better in this respect - just drag the "roller" to "paint" whatever hours you are available.
The down-side - no apparent option to keep participant availability hidden. There's always something...
