This now seems like a stupid question, but I can't figure out how to change it.
In the forum, if I click on my name, it shows me my profile, and there's a change password button.
But if I click on that, I'm prompted to sign into the Wiki, and once I'm logged in there, I cannot find anything related to account management.
(If I click on my name in the top bar of the Wiki, it takes me to a page I can edit, presumably about me. But I can't find anywhere to edit account preferences.)
