+# Gravatar Plugin
+by [Klaus Weidenbach](http://friendica.dszdw.net/profile/klaus)
+
+This addon allows you to look up an avatar image for new users and contacts at [Gravatar](http://www.gravatar.com). This will be used if there have not been found any other avatar images yet for example through OpenID.
+
+Gravatar is a popular, but centralized and proprietary service where people can store an avatar image for their email-addresses. It is widely used on many pages, for example to display an avatar for comment functions, profile pages, etc.
+
+* * *
+
+# Configuration
+## Default Avatar Image
+If no avatar was found for an email Gravatar can create some pseudo-random generated avatars based on an email hash. You can choose between these presets:
+
+* __Gravatar__: default static Gravatar logo
+* __MM__: (mystery-man) a static image
+* __Identicon__: a generated geometric pattern based on email hash
+* __Monsterid__: a generated 'monster' with different colors, faces, etc. based on email hash
+* __Wavatar__: faces with different features and backgrounds based on email hash
+* __Retro__: 8-bit arcade-styled pixelated faces based on email hash
+
+See examples at [Gravatar][1].
+## Avatar Rating
+Gravatar lets users self-rate their images to be used at appropriate audiences. Choose which are appropriate for your friendica site:
+
+* __g__: suitable for display on all wesites with any audience type
+* __pg__: may contain rude gestures, provocatively dressed individuals, the lesser swear words, or mild violence
+* __r__: may contain such things as harsh profanity, intense violence, nudity, or hard drug use
+* __x__: may contain hardcore sexual imagery or extremely disurbing violence
+
+See more information at [Gravatar][1].
+
+## Alternative Configuration
+Open the .htconfig.php file and add "gravatar" to the list of activated addons:
+
+        $a->config['system']['addon'] = "..., gravatar";
+
+You can add two configuration variables for the addon:
+
+        $a->config['gravatar']['default_avatar'] = "identicon";
+        $a->config['gravatar']['rating'] = "g";

+Addon for Friendika to include MathJax (LaTeX math syntax)
+
+This addon lets your users use LaTeX to type mathematical formulas
+within their posts. MathJax takes care about the best method for the
+browser to display the formula and provides compatibility to 99%
+of the modern browsers.
+
+You can either use the MathJax CDN online, thus loading the required javascript
+libraries from the MathJax cloud, or use a local installation of MathJax.
+Please see the plugin settings in the admin panel for configuration possibles.
+If you don't set up a local MathJax instance, leave the configuration untouched
+it will fall back to the MathJax cloud as default value.
+
+If you don't use the admin panel add mathjax to the list of active addons
+
+$a->config['system']['addon'] = [..., mathjax, ...]
+
+To select the source of the included javascript libraries add a line
+
+$a->config['mathjax']['baseurl'] = 'the URL to your MathJax installation';
+
+to your .htconfig.php file. If this line is not there, the addon assumes that
+you want to use the MathJax cloud (CDN).
+
+Please note that your usage of the CDN is governed by the "MathJax CDN Terms of
+Service" see http://www.mathjax.org/download/mathjax-cdn-terms-of-service/

+TestDrive
+=========
+
+
+Testdrive is a Friendica plugin which implements automatic account expiration so that a site may be used as a public
+test bed. 
+
+When an account is created on the site, it is given a hard expiration date of 
+
+
+$a->config['testdrive']['expiredays'] = 30;
+
+Set this in your .htconfig.php file to allow a 30 day test drive period. By default no expiration period is defined 
+in case the plugin is activated accidentally. 
+
+
+There is no opportunity to extend an expired account using this plugin. Expiration is final. Other plugins may be created
+which charge for service and extend the expiration as long as a balance is maintained. This plugin is purely for creating
+a limited use test site. 
+
+An email warning will be sent out approximately five days before the expiration occurs. Once it occurs logins and many 
+system functions are disabled. Five days later the account is removed completely.
