I don't mean that additional usergroups have been imported, but that xenforo seems to be using two separate and distinct sets of usergroups.
On the one hand, there are the familiar usergroups:
1. Unregistered / Unconfirmed
However, there appears to be an additional set of usergroups:
This has caused confusion after importing, not least because:
a) Setting a member up in the moderating usergroup, with relevant permissions, will not apply - unless the explicitly selected with Users > Moderators > Add Moderator
In other words, it looks like a separate usergroup system is running alongside the familiar usergroup one. After all, why have the option to set up a usergroup for "Moderators" with various moderator permissions available, if this will not work without the second "Add Moderator" selection being applied?
b) Additionally, using the spam cleaner, and checking the option"Ban user" so far results in the banned member continuing to display as in the usergroup "Registered" when I use my admin account to edit their backend profile.
It's as if banned members belong both to the familiar "Registered" usergroup, but also an additional - and invisible - "banned" usergroup.
My question is whether I have completely misunderstood the situation? Because at the moment it appears there is a parallel usergroup system running alongside the familiar usergroups, and I don't understand that.
EDIT: Right, just seen that I hadn't set "banned users" to "Add User Group on Ban". My apologies! And I'd delete this thread if I could. However, I still don't understand why the "Moderating" usergroup appears to work distinct to "Add Moderator"?
