I think at this stage in the game written votes should be counted as an extra vote, obviously provided it's not spam. There will be a TON of debate as the final 4 duke it out, and likely some very well arguments as to why people think their pick should win. If someone feels passionate enough about the game they wanna see win, let them prove it.
Obviously, each person should only be aloud to make one written vote, as well as one pole vote, making it two votes per person. Common sence there.
Does this count as a second vote?
