I just found out about Zcash via a Bitcoin and cryptocurrency faucet forum called faucetlove.com where they have a Zcash discussion area:
http://faucetlove.com/viewforum.php?f=133
There is not a lot there yet and i think the forum is quite new but i found it via google recently and bookmarked it since the bitcoin faucets were all working ones and it has some cool stuff so i thought i would share the link here
