Very easy way to draw teams for a blind draw....at the close of the season: You could randomly number each of the participants.... send that list via a private message to at least one member ( not involved in the draw) - at the same time have another member put numbers in a hat ( say 1-20) and and pair them up - you could do 2 teams or however many you want... just have whoever draws them assign each number drawn to team 1, next one to team 2 , etc... then just have that person post the numbers/teams. Then the person who has the randomly assigned names can just change the numbers to names ( and third party will have them to verify).
I think the idea of a blind draw will work well, as I have read that in years past some people "disappear". so at the close of the season you can just put in those who have stayed active. Downside is you can't pick teammates and root for them all season, the upside is any and every posted deer COULD be your teammate! Just a thought.... looking forward to contributing some horns....
