Yeah, but copy/paste the post above you to record your "votes". So it's easy for everyone. I should have demonstrated.
With what you just posted, you would say:

[b]Seravee - 20
Lady Squee - 20
Goldmarble - 22 (+2)
mdk - 18 (-2)
ImANargleHunter - 20[/b]

And then the next person would copy what you just put and then record their votes.
