PBEM challenges

[stockwellpete]

When I was setting up a scenario challenge it has two boxes called "First Side" and "Side". Presumably "First Side" means the first side to move, does it? If so, what is the purpose of the "Side" box? And what happens if you inadvertently put the same army in both boxes? Anyway, it is very good if you are able to change who moves first in a scenario.
