WHAT YOU NEED TO DECIDE
* time
In Italy, we wanted to go from 24 November at 00.01 till 1st December at 23.59.
* scoring
In it.source, we will probably award 3 points for every proofread page and 1 point for every validated page.
* awards
Last year, it.source only allowed to validate pages (and not to proofread).
We awarded the first prize to the "user who validated more pages".
The second and the third prizes instead were randomly extracted from the others: but the more pages a user validated, the more chances he had.
Every validated page (or point) counts as a lottery ticket: the more I have, the more chances too.
I believe everything can be easily adapted if you both allow to proofread and validate at the same time
I really hope many Wikisources will be present this year :-)
