Beneath each posting box is an area to add Labels to your post. Click "Show all" to see all available labels. Select your last name(s) and other tags that apply to your post from the list. Add new ones (i.e."Rio de Janeiro") that will be relevant to other blogger posts by typing them in the Label box.
Note: A single post may have up to 20 labels. Because this blog has more than 20 authors, a second post was created for the purpose of creating labels for them. Labels are used to generate the tag cloud on the home page so family and friends can easily find your posts by clicking your last name.
