List of things to do to the wiki I don't have access rights for.
I will not edit this page often, nor without a lot of thought.
You log into both the main website (forum) and wiki through the same inteface. The website logged-in status seems to last forever, but the wiki considers you logged out after a short while (less than a day).
To log yourself back in to the wiki, all you need to do is visit the main site's login/logout page. You don't actually need to log in or out again properly.
PITA for those that don't know the quick workaround: and manually log out through the main website (twice, because the first try always fails) and back in again to fix their wiki login status.
