BOTM nominations?

[TECK]

I don't understand one thing:
How boards are selected?

Ok, after reading Kerry-Ann's entry, I'm a little puzzled.
BOTM is based on a simple nomination system. The five boards with the most nominations within the month are entered into a final poll. All licensed members are then able to vote for their favorite board amongst the five final modifications.
The 5 boards that have the most seconded nominations will be placed in the poll in alphabetical order.
In other words, if a board will be nominated by several members, it automatically enters the contest. Since the participation rate in this community is very small, is enough for me to post a thread to my forums and many users will vote for my board? Or do they have to be vBulletin licensed members? If they have to be, then yes, is fair.

Voting is up to the voters; no one can force or rally a vote, please visit all nominated and vote for the best board.
What "best" means in this context? Best design, best code modification? Is not clear at all.
Also, how come on every contest we always see the same type of board, with little graphics changed, but nothing original? There is nothing inovative about those boards, to be named Board of the Month.

Help me understand. Thanks.
