Crashfu, I think you're a little mixed up on what people had in mind.
Individual players disabling skins would not necessarily stop other people on the server from choosing the skin they want; it could simply display them as something else. That would be the real win-win. Everyone plays whatever skin they want, and only the skins that they want displayed get displayed, without the hassle of getting to know the exact tastes of every server admin on the browser. A little bonus, people running the game on toasters could load just one player model, if they wanted.
Was agreeing with Crashfu, but yeah this sounds better even maybe.
Also, big realisation, this is already very easy and possible to do with KF1 just by modding a bunch of ucl files (any chars that you don't want to see can be Masterson for example).
Maybe I should cook this up in a day then no-one will be able to complain about KF1 chars again.
