In the Address Book :

- For each person you want on the committee: navigate to their addy in left
pane
and click on Select-> to copy them into right pane
- OK to finish

In OE when composing a msg, just type the Group name in the To: field.

I don't think the "folder" really matters.

In the message composition window, click on the To to open the Select
Recipients window.
Highlight the group name.
Add to To or add your name in To and add the group name in Bcc.

To create a group of contacts:

You can create a single group name (or alias) to use when sending a message
to several contacts at once. Simply create a group name and add individual
contacts to the group. Then, just type the group name in the To box when you
send e-mail.

 1.. In the Address Book, select the folder in which you want to create a
group. Click New on the toolbar, and then click New Group.
 2.. The Properties dialog box opens. In the Group Name box, type the name
of the group.
 3.. There are several ways to add people to the group:
   a.. To add a person from your Address Book list, click Select Members,
and then click a name from the Address Book list.
   b.. To add a person directly to the group without adding the name to
your Address Book, type the person's name and e-mail address in the lower
half of the Properties dialog box, and then click Add.
   c.. To add a person to both the group and your Address Book, click New
Contact and fill in the appropriate information.
   d.. To use a directory service, click Select Members, and then click
Find. Select a directory service from the drop-down list at the end of the
text box. After finding and selecting an address, it is automatically added
to your Address Book.
 4.. Repeat for each addition until your group is defined.

Note

a.. To view a list of your groups separately from the Address Book listings,
in the Address Book, on the View menu, make sure that Folders and Groups is
selected.

b.. You can create multiple groups, and contacts can belong to more than one
group.

If you want to send to a group without all the addresses being shown to each
recipient, open the Address Book and make a new entry. Enter the group name
in the Display field, but use your address. (Some ISPs require a legitimate
address in the To line, and the recipients will know it is from the group).

Click the To button | Enter the group name using your address in the To
field | Enter the Group in the BCC field.
