Being able to build the game is not all, but a good start. Next will be that the test team gets an idea of how serious you are about helping, especially when things are not only fun. A good start is to help testing reports in the bug tracker, especially unconfirmed ones, or ones that are not clearly reproducible.
Thanks, its my first time actually using Terminal, and i've come across an error at almost every step, so its taking a lot longer than I thought, but when I get there, i'd also like to add to the tutorial, and update it to make it less confusing for other new testers.
That bieng said, are there any devs that run OSX? Kayden, RlyDontKnow and Pizik have helped out alot but they don't run OSX.
