Oh man. I love this addon!
I had been using Farcaster's event attendance 1.2.0, but after installing this mod, was unable to see the event title in the calendar, nor was I able to respond to the rsvp function in Farcaster's event attendance hack. Well, then I found Farcaster's Event Attendance & vB Event Forums Integration addon:

Now everything works like a charm! I can post events from my calendar, and it takes me to the events forum. Or I can post a New Event from within my forum and it automatically adds the info to the calendar. I can also RSVP so that an event attendance roster is created! AWESOME! It all works like a charm. Thank you!
