The Falcon's Nest

There are two ways one can make groups of contacts in Opera's email client.

The first makes static groups. This is done by creating folders of contacts -- in the Contacts panel, use the toolbar at the top to create 'New folder' and give it the name of the group you want to create. Now copy the contacts you need to be in that group into the folder.

Note that this is kind of dumb in the sense that if a contact needs to be included in more than one group, there need to be that many copies of that contact. If some information for that contact changes, one has to edit all the copies.

To compose a message to this group, select its folder and click on Compose (or Shift+Enter, or right-click and select Compose). The email composition page includes all the contacts in the folder in its To: field.

A much better way to make dynamic groups. This needs only one copy of the contact, and allows the contact to be part of multiple groups easily.

To create such a dynamic group, one needs to use the Notes field in the contact's properties. Right-click the contact in the Contacts panel, click on Properties and select the Notes tab. Now add a unique word in the Note corresponding to the group you want the contact to be part of (e.g. family, jokes, friends etc).

When you want to compose a message to a particular group, enter the word for that group in the Quick find field in the Contacts panel. This will only display the contacts in that particular group. Select them all (with Shift+Click or Ctrl+A), and hit Compose.
