so uh modelow's plan sucks here's why. first of all, there has been many cu playtest builds leaked yes, but applying to be a playtester isnt possible, the playtest applications are over and you can no longer be apply for playtester, once in a while loy will do a token team application so they can do cheesed up faster, SO we need atleast someone good with gamemaker here to apply when that happens and when you get the build and become a token member, leak it.

you can also have experience with modding PT and not just other gamemaker games thats fine you'll get higher chances on being applied, you'll also have to understand Gamemaker's coding language, oh and yes you need PT, so you would need to verify then apply. and if you do mod other gamemaker games and PT that'll also make your chances higher.
