If you're participating in a signature campaign, the first thing you should look at is the rules. Because every manager of any signature campaign always writes the rules at the beginning for the participants who will participate in it. But if you take part in a free campaign like the one you are using now, I don't think there is too much work for you to do that because on the front page of the signature campaign the rules are very clearly written and I think they are very simple to understand.
