Does the forum platform support voting anonymously?

[RJDan]

I am looking at how to organise the voting for the Community Favourite Awards.
The easiest is to have people vote openly on the forum (ie I post the nominees as comments and people can up vote the nominee/comment they vote for).
But this is not anonymous nor does it restrict it to one vote per person.

Does the forum platform have a 'survey' or poll function?
