This is a suggestion for a default feature.
This will slowly make Blockland similar to tf2, but probably earn Badspot a crapton of money in the process.
Basically, Badspot would be able to design a taunt system similar to TF2's, and have taunts be submitted through the steam workshop. Badspot approves them, easy money. More money means more development. More development means more happy campers.
I'm also thinking there should be a Blockland Store thing that sells hats and taunts.
Note that this was inspired by
this and is probably a bad idea.
