Figured this should go into policy feedback since it already exists as a feature in the game and it’s a matter of who the admins allow to use it.
I think fax responders having access to HTML while preparing forms, the same way staff do, would allow them to express their creativity in a near-infinite amount of ways and prepare very interesting forms and messages.
Seeing as Fax Responders are a whitelisted role, I believe there would be a much lower chance of CIC being faxed a screenshot from a cartel beheading video.
