Cheaper to just set up a group text message and email system on your own phone as long as the group has the technology. One call now is good, we use it at work, but I prefer getting a text message, that way there is something written down and people can use it as a reference if there are changes. Plus, most girls have their own phone and are quite savvy! Maybe your daughter could show you? Just a thought! They always know how to do those little tricks first!!
