Support for the MSTW Schedules & Scoreboards plugin is being phased out. The plugin will continue to be maintained on the wordpress.org plugin site in support of legacy users, all new users should go with the MSTW League Manager plugin, which is very actively maintained. Legacy users of Schedules & Scoreboards should also consider migration to League Manager for improved features and support.
It is still available on the WordPress.org site, and the documentation will be available on this site. So it can still be used, and it will work with future versions of WordPress for some time. If there are bugs, I will look into them. However, the plugin will not be enhanced in any way.
While the name might sound like overkill for small, simple sites, it really isn’t. While League Manager provides more features and advanced features for larger, regional sites, it can also be used just like Schedules & Scoreboards for simpler sites without the need for advanced features. So there is really no need to use MSTW Schedules & Scoreboards or continue to support it (at the expense of the other MSTW plugins).
