Here are my thoughts on the details/steps:
1. EA posts the attachment that they have in mind (or, better, a "your choice of these 3 attachments") as the start of a nomination thread (the main reason being that if someone already has a backblade, they may not be as interested on building one as they would be to make a boxblade or a landplane)
2. Make a "Nomination period" of 2-3 weeks where people can be nominated (or can nominate themselves) to be in the poll by posting in the thread from step 1
3. Close the nominations and put in a link to the poll with all of the options (perhaps actually close the thread?)
4. Have a 1-2 week period where people vote on the nominations (the Doodle poll could work, but the voters would have to use their screen name in order to validate their vote)
5. Whoever runs the poll closes it and posts the results (either to here, or via PM/email to EA)
6. EA announces the winner
7. The winner builds form the kit with copious amounts of pictures posted to TBN
Does this seem fair to all interested?
Thanks
