Oh, so that's like the special title given to people that contribute to developement?
No, that's a very specific title given to a specific someone who actually was part of the Sandswept team.
Like if I made a crowbar that made it into TDL I too would get the "Honourary Polypusher" title?
That would be a different title (and/or achievable). People who contribute stuff to the game when we get that system set up will definitely get some forum title/achievable of some kind.
(But you wouldn't care, right? Because it's meaningless? ;)
You'd likely also get a special variant of your item in game.
