The thread just seems to have died off without a winner declared.

It kinda did. But the instructions were this:

To vote for you favourite nominees, simply their username on the thread.

I assume the word "post" is missing. Then my next assumption would be that all naminations would count as votes too.

Nominees
1. n0nce 1vote
2. nullama 0 vote
3. SatoPrincess 1 vote
4. KingsDen 0 votes
5. mynonce 0 votes

So there's a tie between n0nce with 1 vote, and the thread starter with 1 vote Cheesy
