I want to send a message to all of the people with whom I went to college.
I had all of my friends grouped so that I could search for them all together, but now I (1) don't know how to access that list and (2) if I do find that list, don't know how to do a message to everyone on it.
Can anyone help?
The easiest way to do it is via the Note option. Go to your Notes feature and select "write a note" You can then choose the privacy option and select a preset list of people who can access it.
Otherwise if you use the message feature you will have to type in each persons name.
