We had a full model UN in high school. Since all the seating was assigned ahead of time; the vote-keeping was done entirely on pre-printed ballot sheets. basically in the format:
Sheet 1
Name: Y N A ...
Name: Y N A
Total: [blank] [blank] [blank]
And they were based on the seating at the university's lecture hall we used, they all listed countries in order as they were seated, starting with the centre.
You pass out the sheets to the centre people, and then they pass it along to the end; they're forwarded up;
At the front: Tallied per sheet;
the totals transferred to the log sheet
Sheet 1 :[blank] [blank] [blank] ...
Sheet X :[blank] [blank] [blank]
Totals :[blank] [blank] [blank]
And you had totals, with fairly rapid turn around and summations. Secret votes just had a stack of paper with "Country: ____ Y N A" and they were required to fill it out and put it into the box going around. to be condensed and summarized onto the above formattetd sheets at the front by the two lackies.
Junk character filter? Really? I wonder what the threshold is. Wow, this really makes it a bit difficult to nicely explain the formats, but then what can you really do about it. I wonder what the thresholds are.
