the sooner you pick a number, the sooner you will have the dates and time to prepare

Hi,

Please inform your friends to choose a number. There should be two groups for each number (one from Group A and one from Group B). There are still numbers available to pick. You should understand that it is about the presentation that you will have in two weeks time. So the sooner we finish with the lottery the sooner you will have the dates available so students who will be the first will have more time.
Please make sure you notify all groups to pick a number as soon as possible as the time flies ...

Thanks,
