I know it's not exactly what you want to do, but for your information, you can copy & paste an event to a different calendar using the usual key combinations.

I have just test, the usual keys doesn't work (Firefox 3.6 and chromium 9.0.597) :-/

I want copy an event by drag and drop on a new date/time. (usual keys for copy at an other week would be useful too)

This feature would be great.

I have to create events with more than 10 participants.

Without a duplicate or a create from features it's very painfull.

As francis already said!

The workaround is to copy the event to another calendar by:
1) selecting the original event
2) press <CTRL>+C keys for "copy object"
3) select another calendar in the list on the left side
4) press <CTRL>+V keys for "insert event"

Now you have 2 Events with the same content, name, invitees, start and end time in 2 different calendars.
Edit the one event you copied, e.g. by setting another start time, add another invitee and switch calendar.

A workaround is not a fix.

I understand I must create a special "copy&paste" calendar ?

Seriously...

To have a workaround is better than not having one :-)

No, you can use every calendar you have write privileges for. It only has to be different from the calendar with the original event.

Now possible in v3.
