I will confirm this for sure when I get confirmation. I think we can start the voting process before the end of funding, just take a snapshot of votes at the end of voting. bter will setup a special voting page. For NXT AE TOKEN the following two addresses are how to vote.

ApproveBonus NXT-GR5T-8W3L-UFQP-8VFPV
RejectBonus NXT-FCHV-C8VL-YWFJ-EELVV

The last tx you do to either of the above accounts will be your vote. valarmg will have the details on what tx is supported. I think sending any message will do.
