What vote?
There's a voting process every month, it ends on the 1st at 00:00 UTC.
1 BARR = 1 vote, sent to the BARR Market Fund with a message attached naming the altcoin being voted for.
(NXT-59NQ-AA5B-V4NT-HAZLY)
The Market Fund exists only to trade BARR, and no BARR or NXT ever leaves that account unless it goes back to the Burn Fund. So voting also acts as a donation that helps support the price of BARR.
After we get enough users in OFFS, we may transition to burning all BARR that comes into the Market Fund, swapping it for OFFS, selling the OFFS for NXT, and then using 100% of that NXT to buy BARR. Then burning that BARR, etc.
So far nobody has voted except me, but it's still good because it's an open process that is available for everyone to see.
