Code gists to help when running Theme My Login on Multisite with PMPro

my_template_redirect_membersonly.php

/*
    This is a collection of code gists that can optionally be used when running Themed My Login on a multisite network
    to help things flow better.
    
    Be sure to NETWORK ACTIVATE Theme My Login.
    
    To be specific, this setup is meant for cases where users registering at the main site are gaining access to a "membersonly" subsite and users should effectively have a WP user account on all subsites within the network. i.e. all of the subsites are parts of the main site instead of completely different sites.

/*
    Keep non-admins out of the dashboard. 
    
    TML will send network admins to the profile page on subsites if they aren't also admins of the subsite. So we don't use this instead of Themed Profiles options to keep non-admins out of the dashboard.)
