I'm already starting to see some questions and answers becoming lost in the annals of the ZScript Discussion thread, so I'm starting this up to help keep questions related to how X/Y/ZED works here, and to talk about current documentation accuracy.
THE BIG FAT LINK TO ZSCRIPT'S DOCUMENTATION EVERYONE WANTS is still under construction.
All contributions and examples of code for this would be greatly appreciated since flying solo on this is quite difficult. Not to mention my knowledge on how a bunch of this stuff works is limited.
