You might be wondering how Google groups differ from the contact groups you can create in Google Contacts. The primary difference is that a Google group has its own email address, so others can use it. Your contact groups, on the other hand, are for your personal use, to make it easy to add a list of addresses to your email messages and meeting invitations. Contact groups don't have their own email address, so no one else can use them.
All the groups that you belong to are listed on your personal My Groups page. To access your page, log into UWF Gmail and click the more drop-down arrow in the upper-left corner, then select Groups.
To create a new group:
After creating your new group, you should review the settings. Group settings, accessible from the right-side column, allow you to customize how your group works including who can join, who can view messages, and who can post messages. Also through settings, you can change the colors, fonts, and navigation.
To send an email message to a group, simply enter the group's email address in the To field of a standard Gmail message. You can find the email address for the group on the group's main page. The first time you send a message to a group, you may need to type the group's complete address. After that, you can just start typing it, and it will auto-complete.
Keep in mind that the group settings dictate who has permission to send to the group - permission to send messages may be limited to the group manager, group members, people at UWF, or it may not be limited.
In Google Docs, Sites, and Calendar, you can share to all the members of your Google Group at once by entering the group's email address. When members are added to or removed from the group, the changes are immediately applied to Google docs, sites, and calendars. Instructions
