Error: I'm trying to figure out how to use “responsibileeditors-changeresponsibility”, “responsibleeditors-takeresponsibility”, and “responsibleeditors-viewspecialpage” permissions.
Solution: responsibileeditors-changeresponsibility - Only users that have this permission can actually access the "Change responsibility" dialog from the more menu. There is one exception: A user that is assigned as a responsible editor can do also, even if he has not the appropriate permission responsibleeditors-takeresponsibility - Only users with this permission will show up in the list of available responsible editors in the "Change responsibility" dialog responsibleeditors-viewspecialpage - There is a SpecialPage that allows to retrieve information about and change responsibilities that are set. It's more or less a admin tool, but can also be used by normal users.
