Okay, so we've launched our M2P-based membership scheme and things seem to be going okay (to the extent we can tell at this early stage), however...
Our M2P instance is running in network-protection mode.
While we can see billing information, new members don't show up in the M2P Members (wp-admin) page unless they have some role relating to the site that holds the M2P pages.
Since rootsite (where M2P's pages are) is pretty much only used for operational matters (such as managing memberships), this means it's going to be difficult to review current memberships, and probably difficult (or maybe impossible) to edit memberships manually if required.
Is it just me, or is this an oversight in M2P's network mode?
ETA: Something that may be relevant: I've gone to some lengths to disable M2P's account registration mechanism because it doesn't validate email addresses (and therefore provides a mechanism for spammers to create bogus accounts). Therefore, all M2P signups are done using pre-existing accounts that have no role on any site.
Maybe I need to write a hook to assign a subscriber role to rootsite on creation of new account?
