Support Forum

I am trying to control which group a new forum member is assigned to when they first register on the forum.  According to your codex:

However, I cannot see anywhere under this option that allows me to set the User Group:

I have 3 User Groups in addition to the Guest group - Forum Members, Club Members and Committee.  When someone new joins the forum I need them to be automatically assigned to the Forum Members group.  I have just added this group.  Previously I only had Members and Committee and new registrations automatically went into the Members group, but I have now re-named Members as Club Members and created the new group of Forum Members, so as I cannot see a way to change the default user group I am concerned that new registrations will still go to the Club Members group as that was previously the only Members group available and was the default.
