We compile and process the list about once every 7 to 10 days.
Oh, I just didn't knew that. In e-mail was: "Simply post the message below at
http://bitcointalk.org, with a screenshot of your win and we shall credit an extra $5 worth of bitcoin into your account
within 48 hours!"
OK, I'll ask him to change the wording in the email
He told me to compile the list from the thread about once a week and it usually takes a few days to get credited after that. Should be sometime at the end of next week for the next one.
