I have registered for the ugChain twitter bounty few days ago, But I was able to do only 2 retweets so far for the (29/11 - 05/12) week. So I can't submit reports for this week. Can I participate in from next week (05/12 - 12/12) which is starting from tomorrow ?

I need a help from any official member, I want to change the bitcointalk username and the profile link on twitter and facebook bounty spreadsheets. May I know is that possible.
