My fiancé and I work at a k-12 private school. Between us, we have quite a few staff members that we are close to and would like to personally invite. However, there are a good number of staff members that we have little or no connection with. How do we invite staff personally but not offend those we feel no connection with if almost all staff are making the invite list? One suggestion was a combination of personal mailed invites and a bulletin board invite (please fill out the RSVP card if you would like to attend and slip it in my box)
