MSTW League Manager

All the normal installation methods for WordPress plugins work. See the installation manual page for details.
Upon installation make sure your site’s WP default timezone is set correctly in the WordPress Settings->General screen.

NOTE: If you are using MSTW Leauge Manager Add-ons plugin, YOU MUST INSTALL VERSION 4.8 OF BOTH PLUGINS. If version 2.7 is working great for you, there is no need to update unless you really want to try one of the new items.
