The current forums are going to be taken down at somewhere in between 2019 and 2020 (Maybe in December 2019), so the only way to make a profile active would be to make a contribution directly to an article.
The message walls are going to be replaced (Will retain the same name though) btw. Let's hope that the message wall post addition/edition will remain to count as a contribution.
