Randy and tech guys:
Why not send a mass Private Message to all members reminding them of the vote? It seems to me this should be easy enough to do and would definitely get out the vote without any major intrusion (such as a popup ad) or any "unknown labeling" after a member has voted.
In general, I agree with the sentiment of this thread and I do not feel that, by default, the "I Voted" avatar should be shown. I do disagree with some of the statements (both factual and not) made about the U.S. election system and agree that this topic does not belong in this thread.
