I have meetings on my calendar, that I'd like to be able to forward to someone. It wasn't my meeting, so it won't let me add an attendee to a meeting. I use to use ICS inspector to inspect and save the ICS file off of my calendar into a separate file, and then forward that file to me. That was a bit cumbersome but was the only way I'd ever been able to forward an invite. Now, I'm using the new beta of Thunderbird, and ICS inspector isn't compatible. How does anyone use Lightning, if you can't forward a meeting invite from your calendar to someone? I've always thought that should be something a calendar should handle. it appears from searching that internet that maybe Lightning had that capability at one point in its history. I see references to a menu that existed, but doesn't seem to in the UI anymore.
