What should we do before we start to recruit volunteers?

Summary:

Plan what's needed and how the work can be divided

>From Baby Safety Shower: Recruiting and Using Volunteers at
http://ericps.ed.uiuc.edu/nccic/pubs/babysafe/recruit.html:

You'll need plenty of volunteers to prepare for the shower and then help on
the day of the event. Start recruiting early.

Decide how many volunteers you want and what they will do. Volunteers can
head committees, solicit sponsors, collect donations, set up equipment, make
decorations, greet guests, run game workshops, serve food, clean up, and
much more. Plan to line up more people than you need, in case some drop
out before the event.
