Installation: There are two folders, first replace the /actions/register.php, and then copy siteaccess/ folder inside your mod directory. Goto -> Administration -> Tool Administration -> siteaccess -> enable

Walledgarden: I suggest setting Site Access at the bottom of your plugin list so that it functions properly and loads last, for security measures.

Upgrading: make sure to goto settings and click save.  This is no longer necessary unless you want to change some of the options.

Plugins Replaced: (Deactivate the following Plugins) uservalidationbyemail walledgarden coppa
