Since upgrading to Snow Leopard I have been completely unable to send invitations to events through iCal. Everytime I tried to send an invite I received the following error message:

XXXXXXXXXX currently can’t be modified. To discard 
your changes and continue using the version of your calendars  
that’s on the server, click Revert to Server. To save your 
changes on your computeruntil the problem is resolved, 
click Go Offline.

I finally got around to researching the problem this morning and cam across a helpful discussion on the apple support boards. It turns out that the problem was that my timezone wasn’t set properly in iCal. Here’s the solution that worked:

If you go to preferences within iCal, you can select “Turn on Timezone Support” ( in advanced tab)

then, on the iCal window, top right you’ll see “Eastern time” with a dropdown. Select the dropdown, and “Other”. highlight our geographic region on the map and select “City” as the closest city.

THEN, be sure your system timezone is set appropriately as well.

My invitations are now going out as they should. Hooray! My Entourage-free life has finally arrived.
