why? you wanna be one? huh huh????
you pretty much just get to try out features that havent yet been applied to the rest of deviant.
But some of them might now work properly...which is one of the downsides...
i havent had any issues yet though...so its all good.
If you wanna be one just go into your settings,
and you'll see a box asking if you want to be an official beta tester, and if you wanna be one you just check the box.
