Somewhere along the way, Thunderbird's calendar has stopped being able to send meeting invites to people anymore. The "Notify attendees" checkbox is greyed out on new appointments. Any idea how I might go about fixing/diagnosing this problem? I'm on Fedora 13 with Thunderbird as follows: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.10) Gecko/20100621 Fedora/3.0.5-1.fc13 Lightning/1.0b2pre Thunderbird/3.0.5 - Julian -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
