Hey have you figured out how to add an attendee to a meeting/appointment? The manual speaks of clicking the wheel to add an attendee, but this item does not show up in the menu. So far that's my only beef with the 8700r.
you have to be on a BES to invite attendees. Alternately you can send appointments by MMS, but the recipients unit would most likely have to be able to accept mms, but I am not 100% about that.
