I have created a user group promotion from registred user to another group, when I user reaches 5 postings. Will the user automatically loose the old user group (registered) when he is being promoted? I see to toggle between changing group and additional group.
There's a User Group Promotion cron in the ACP which runs every 20 minutes. Note that promotions are only applied to recently active users. Any who aren't active will (immediately) have any relevant promotions applied when they next visit the forums.
