I suppose it'll be clear once we enter that stage, but I would like to write about this for the blog, so it would be handy to know the details now, rather than in 4 days.
Click this link, and read the sidebar. Looks like each tab on the election page is self-documented a little:
In the election phase, 10 candidates advance to final community voting. Any community member with 150 reputation may vote in the election.
Each community member has 3 votes. Please cast your votes in order of preference, starting with the most desirable candidate first.
All candidates are displayed in random order.
The vote tallies are private until the election is complete.
After 4 days, the final voting results will be freely downloadable from this page forever, and we will calculate the winners using OpenSTV with the Meek STV method.
