What about having keywords for each contact so that if you wanted to
send a group email, you would use the keyword instead of having to
create individual groups or going down your list of contacts and
selected each one.
For instance, you are involved in a few organizations so each contact
that is a member of Circle K International you would put "Circle" or
"Circle K" as a keyword and if another contact was a member of Circle K
but also helped out with the local food bank their keywords would have
"Circle K" and "Food Bank", etc.
Just a thought.
