W4OS is a WordPress plugin for OpenSimulator grid management. It allows users to register for an avatar and choose a starting outfit. It also provides useful blocks that can be displayed on any page, sidebars, headers and footer (via shortcodes, widgets or Gutenberg blocks).

It is pretty easy to set up, so you can start accepting new users within minutes.

The project is sponsored and developed by Speculoos World and Magiiic.
