Look under the one you are interested in. For example, if you are interested in signature campaign and for example it says 100,000 tokens allocated for signature campaign. The 100,000 tokens will be distributed among the participants in signature campaign.
As for the stakes, you will receive 0.5 stake per week you are with the campaign if you are a Jr. Member. The bounty manager will add up the stakes you have earned. For example, you have been with the campaign for 4 weeks, you will earn 2 stakes since 0.5 stake X 4 weeks = 2 stakes.
When the campaign end and there are total 1000 stakes earned by all participants. The calculation will be: 100,000 tokens / 1,000 stakes = 1000 tokens per stake. Now you have 2 stakes, you will receive 1000 tokens X 2 stakes = 2000 tokens.
This makes it clear now! Your a saint!
Almost a Year later.. Thank you for clarify to me!! I was assuming something like that but was no pretty sure!
