Hey ladies

Quick question. Can you correct me if I am wrong or add anything I missed but below is what I think is the proper etiquette for small intimate wedding where many people won't be invited.
1. Only send out engagement announcements to people who are invited.
2. FB is okay, i.e. status update (after important people are told)
3. If engagement party, bridal party or bachelorette is asked to be thrown, only invite people who will be invited.
4. Invite your guests

5.Wedding announcements can be sent to everyone even those not invited i.e. distant relatives and friends and coworkers
