Should the guests on each week be credited as "Self - Panellist" or "Panellist"? The series regulars (Sam and Ed) are credited as "Self - Panellist" but each weeks guests are just "Panellist". This also goes for the guest quizmasters as they are credited as "Guest Quizmaster" rather than "Self - Guest Quizmaster", "Host" instead of "Self - Host" when Tom is absent, etc.

I'd argue that they should all be credited with the prefix "Self" (with appropriate designations such as "Panellist", "Guest Quizmaster", etc.) as they do appear as themselves rather than playing the character of themselves. The show also includes a kind of 'catch up' chat with each of them at the beginning (and sometimes throughout) the show, seemingly adding the idea their appearances are as themselves. Other shows with a similar guest format, such as the Australian Would I Lie to You? and Q&A, both consistently include "Self" as a prefix for all appearances.

Also, as far as I can tell, localised character names aren't a thing when switching between languages, so should the spelling of these entries (such as "Panellist") follow the regional variation of the country of origin (e.g., for the Australian version of Would I Lie to You?, crediting as "... Panellist" but for the American version, crediting as "... Panelist" or all stick to one (most likely American) variation? There is an inconsistency in some shows, like both the Australian Would I Lie to You? and Q&A.
