It can send to multiple address emails (separated by coma) and gives the opportunity to add an optional personal message.
This CB plugin is free, GPL and based on the CB1.2 framework.
PROS: It works good, has lots of share choices and is one of very few free available extensions for CB here on JED. That alone is a big plus.
CONS: only one (that I have found) is when the modal comes up it doesn't fade the background page and you have to also click twice on the X in the upper right corner to close the modal.
