Forum:Posting to FB but not to wall?

I want to share my rewards, lost animals, etc wit my FV FB friends, but I'm tired or cluttering my wall with these posts. If I 'Share' my rewards but then skip the publish to wall section, will the FV Game Bar still allow my friends to claim rewards with that 'Bonus' button? Or will not publishing to my wall not allow anyone to claim my rewards?

Also, does anyone know if you can plant crops BEFORE joining a co-op and still be able to harvest your crops AFTER joining?

Thanks in advance.
