One of the things I am looking at doing to help the team out is maybe to try donating some $$$$ so they can maybe expand their team (if that is something that a portion of the funds go to). I am also interested in the documentation surrounding Metro. It seems kinda nifty as a project and could have the potential in helping the project long term.
However, I am more interested in it for a building my own distro based off Funtoo where that is more the focus instead of compiling everything from scratch.
