I’m talking about the forums in particular. The Help docs refer to a log out link that’s no longer there and I can’t find a place to change the password in the User CP, only my email.
The forums are linked to the rest of the website, so logout on the website and you’re logged out from the forums.
Even if my forum account is different from my WP account?
It’s not different from your WP account, that’s the whole point of the integration.
