Hi Garn, I'm janus and I'm one of the admins on this wiki. I don't quite understand your issue with the episode credits. We've listed cast credits on episode pages for years, including separating them into "Starring" and "Guest Starring" – which is how the cast members were credited within the episodes. I'm not sure what you mean when you say it's not being used properly because we don't decide who's credited where, it's literally from the episodes' credits. Many other TV show wikias do this – it's not unique to this wikia.
Regardless we will not be removing the sections without community consensus. If you're interested in pursuing this, then start a thread in the suggestions board. Don't take action (i.e. do NOT remove "Starring", "Guest Starring", etc. headers from any of the episode pages) until community consensus is reached (wait 1-2 weeks make sure everyone has a chance to comment & vote on the suggestion). My opinion is that the sections has been working for years and since it's ain't broken, there's nothing to fix.
May I respectfully request you not use my message wall to continue this discussion, please? Use your own message walls or maybe create a new Discussion forum or something. I've already given my opinion on the matter.
