You could consider giving access to FE beta to some popular Youtube bloggers which make gameplay videos. (Couple of FE fans already made gamaplay videos, but they are not popular enough.) Paradox did this. They gave access to beta of Warlock: Master of the Arcane to a few fairly subscribed Youtube bloggers and voilà 10 thousand views in a single day (all FE beta videos combined have no more than 2 thousand views). Maybe it's too early to make a fuss about FE, I don't know. But this game is too good not to be promoted!
