Hi,

From my experience there are two ways.

1. Go to the bounty's bitcointalk thread and look for "spreadsheet" search for your bitcointalk user name ( Ctrl + F ) and you should see if you have awarded stakes for that week.
2. Go to the bounty's bitcointalk thread and look up the link for their bounty Telegram channel. Join the channel and ask one of their admins to help by giving your bitcointalk username as well as your row number in the FB bounty registration spreadsheet.


Hope this helps!
