Comment 30 for bug 810622

+1 here with the "No writable calendars are configured for..." problem. I only use Google calendars, I have two. I am displaying attachments inline and have checked the setting of calendar.google.enableEmailInvitations and it was false, but even after setting to true and restarting nothing changed. I don't get the drop-down box allowing me to specify which email address each calendar is associated to.

Thanks for your work.
