**Power tags** are an advanced feature which can add extra functions and layout options to your wiki pages (and sometimes research notes). They are entered like regular tags but follow the format `key:value`. After adding a power tag, you must refresh the page. 

To add tags, look for this box at the bottom of a wiki page or research note:

###General power tags 

* `events:foo` displays a listing of research notes tagged with "event" and "foo", and a link to post new notes with those tags in the left sidebar. 
* `sidebar:featured` displays "featured" links and images in the sidebar instead of the usual "related content"
* `style:presentation` hides the wiki toolbar (with Edit, Talk, Revisions) for more formal pages
* `style:wide` removes the 800px width limit from wiki pages, and allows them to flow full page
* `style:fancy` is used to style articles from the GrassrootsMappingForum
* `style:nobanner`
* `parent:foo` adds a bar that links back to a parent wiki page
* `with:username` adds a co-author to your research note with a live link to the user's profile page, however, the note itself will not show up under that user's profile. 
* `lang:es` or `iso:es` is the way to indicate language in a research note or event. In this example, `es` indicates Spanish.

###List of power tags useful for chapter pages:

* `lat:41.023` and `lon:-71.023` latitude and longitude. Together with the simple tag "chapter", the combination of these three tags will create a point for your chapter [on the Places map](/places)
* `events:foo` displays a listing of research notes tagged with "event" and "foo", and a link to post new notes with those tags in the left sidebar. Especially useful where foo = the name of your chapter page. 
* `list:foo` displays recent posts from a Google Group with the name "foo" and a subscription input box
* `tabbed:notes` and `tabbed:wikis` display a tabbed header which offers tabs with links of related research note and wiki content
* `notes:foo` displays 4 recent "popular" research notes tagged "foo" (in grid view, popular means >20 views) at the top of the page, under the tabs if they exist. For example see [Gulf Coast](/wiki/gulf-coast]
* `parent:foo` adds a bar that links back to a parent wiki page, especially useful for places within regions


###Automated power tags, not for manual adding

You might see some of these being generated automatically, like when checking the box for a Research Note to be an "Event" or a "question" or when awarding Barnstars to someone's Research Note. Don't manually add these: 

* `event:rsvp` `date:YYYY-MM-DD` `rsvp:username` 
* `barnstar:barnstarname`
* `question:foo` `response:foo`
