Yup, and one more thing at this moment. You need to manually recount/rebuild forum statistics, since the forum wont do it for you. I tried it multiple times, and the newest user and total number of active users wont update unless you rebuild statistics in forum ACP.

To do this, simply log into forum ACP, visit the tab database backup -> recount & rebuild -> rebuild statistics(the last option). Theres no need to do it every time a user registers though, once per day is what Id like to recommend.
