The system won't let you have 2 requests at the same time. That's why submitting late can be dangerous... you might miss an entire bonus.
You expressed my concern best about posting bonuses stacking up in the queue when I noticed the status of "pending 0 days" going on for several days. The system is not automated enough that when zero (0) days is reached it "automatically" applies the bonus in a member's account. There must be a step before that happens and it involves an administrator's hands-on execution, as far as I can tell. I worried that administration was creating a "bottleneck" for itself in their system. That inaction could lead to a flood of support tickets that unnecessarily slows down that system.
I was relieved to see mine yesterday: Forum Activity Bonus (July17) Sep 9th $3.00 Approved
So that cleared up the queue.
However, administration also moved forward to approve what was "pending" (although the confirmation email sent when you submit your postings says it will take 32 days):
Forum Activity Bonus (August17) Sep 9th $3.00 Approved
I guess someone called an audible on that play.
