I like everyone's comments here, so this is a suggestion:

Let's start a new poll thread where all proposals are posted and everyone can vote for one. One person would need to start this new thread so that all proposals are posted before voting starts. I really haven't gotten the hang of posting pictures in threads yet, and I know that's not an excuse not to volunteer to do this simple quick task, but if someone who does know now how to would volunteer, that'd be great!

I suggest for a timeline:

April 11th: Someone volunteer to post proposals in new poll thread. Perhaps the easiest way to do so is to request that "artists" send their proposals by email?

April 18th: All artists get proposals to thread poster.

April 26th: Deadline for posting thread, voting begins! Deadline for volunteer who'll submit design to manufacturer and handle finances/delivery of coins (Sudinom?)

May 1st: Newsletter released with link

May 21st: Voting Polls close (this is so that I can post the winner in the Newsletter that gets reviewed by the Board through the 31st)

June 1st: Newsletter released with announcement of winning design. Deadline for submittal to manufacturer.
