Simple Availability Calendar plugin is designed for running the availability schedules of registered site users and presenting their availability calendars.
The key controls of the plugin are: 
– Web control for entering the availability schedule for week days 
– Web control for showing availability calendar with appointments booking interface 
– Web control for showing extended availability calendar with appointments booking interface 
– Web control for user’s appointments list
This plugin gives the next main advantages: 
– Shortcodes for all web controls with special parameter for selecting the schedule owner – current user, current post author or user id 
– Customizable date and time format, first week day – plugin uses WordPress site settings, admin can change it from standard WordPress settings page 
– Timezones for users availability schedules – all dates and times will be shown according to the selected timezone 
– Tuning the availability schedule with extended calendar – user can enable or disable certain dates and times 
– Dashboard pages: admin can edit users schedules and appointments 
– Uploading availability schedules for the next dates via Ajax, without page reload 
– Reduced Ajax traffic for better performance and faster data upload 
– Standard form for booking an appointment with email, name and message fields, and captcha for preventing malicious requestszzz
The core plugin control is the availability schedule. Here user can enter his schedule according to the week days. Also it is possible to switch off the whole schedule and become unavailable. And very useful feature for users from different parts of the world – selecting appropriate timezone (by default: site timezone). Control is shown for the current signed-in site user. 
Shortcode: 
 [sa_calendar_schedule]
Availability calendar control is designed for compact presenting of the user available dates and times. Ajax is used for uploading the schedules for next months, so user don’t need to wait the page reloading. User can book an appointment by selecting date and time and filling appointment form.

Extended availability calendar gives more opportunities for tuning the schedule.

FlexiCache is a fast, full-featured and flexible caching system which will improve the performance and availability of any WordPress site.
It is highly configurable to allow unlimited caching rules – expiring different pages at different times, not caching some pages at all, caching multiple versions of the same page depending on browser, language, and so on.
FlexiCache will also work straight out of the box without any need for complex configuration.
<h4>Features</h4>
<ul>
<li>Extensively configurable using user-defined conditions</li>
<li>Handling of high-traffic periods where multiple clients may simultaneously request uncached or expired items</li>
<li>Standalone mode which bypasses WordPress and third-party theme and plugin code to serve cached pages faster</li>
<li>Choice of storage engines: Filesystem, Memcache and SQLite</li>
<li>Pre-caching functionality to cache new versions of pages before the existing ones expire</li>
<li>SQLite indexing of Filesystem and Memcache stores to speed up removing specific items from the cache (automatically enabled if SQLite is available)</li>
<li>Sends appropriate HTTP cache headers to the requesting client</li>
<li>Serves files in compressed formats accepted by the requesting client</li>
<li>Compatible with WordPress MU</li>
</ul>
<h3>Upgrading FlexiCache</h3>
FlexiCache stores config and cache data within the plugin directory (see plugin documentation in versions 1.2.4.2 onwards for the reason why).
If you upgrade the plugin using WordPress’s built-in upgrade process, the entire plugin directory will be replaced, including your config and cache data.
To preserve these, take a copy of the “plugins/FlexiCache/_data” directory before upgrading, and then copy it back after the upgrade is complete.
If you upgrade directly via SVN, this should not be required, since only the files under version control will be updated.
<h3>Deactivating FlexiCache</h3>
FlexiCache can be disabled via the admin interface as with any plugin, however if you are running in Standalone mode, you should remove the .htaccess modifications before deactivating the plugin.
For a standard WordPress install, this modification can be done via the admin interface, however it is recommended that you make this change manually, especially if using WordPress MU, where multiple sites may share the same .htaccess file.
Please see the documentation supplied with the plugin (accessible via WordPress’s admin interface) for more information.
