Click on the email agenda button.

You're presented with list of people or groups who may receive it. Click on one or more.

Also choose who is going to get replies.

It is probably a good idea not to use "club members alias" (i.e. all members) unless it is really necessary. 

Add a custom message if you wish. You can use any of the variables; these will be filled in with the correct options when the email is sent. Place them between outer curly braces and inner square brackets, like this: {[name]}

Click on Send agenda.

If you wish, you can save the agenda as a template for future use by checking the arrowed box. In that case, you'll need to provide a title for the template.
