X13 is officially open for Beta.

Same rules apply as all the previous betas:
 - I've tested it a decent bit, I think everything is working properly, but it may fail at any time.
 - You have to opt-in to see the stats (cookie based, need to opt in once on each browser)
 - Starting off small to contain any issues, only 2 coins to start, will add more as we expand.
 - You're on your own to setup/debug miners, if you know what you're doing, or don't mind stumbling through the setup, go right ahead

Enjoy:
