New in the FirstClass client 16.0 These are the new features in 16.0 that are documented in this help: •       Addressing a message to, or replying to, someone who isn't already on your server automatically creates a contact representing that person. You can turn off this behavior through your preferences. •       File > Open > Communities is now File > Open > FCWS, and the Communities navigation button is now FCWS. •       You can delete a single occurrence of a repeating event to which you have been invited. •       Category and keywords fields on the Info form are read only. Assign these values in objects' envelopes.
