I work at a business that rents equipment to film productions.  From
time to time I check with another business (not a competitor)
regarding leads they may have for upcoming productions.  This is done
on the telephone.  What we need is a template where each of us can
fill in info (production company, phone no., contacts, etc) and get it
to each other quickly.  We both work at computers so I want something
that is fast, re-usable, and notifys us when the info arrives. What
should we use?  email? IM? message boards? groups?  Thanks!
