With regards to the Signature Bounty what exactly does this mean (it is also requested in the Translation bounty too).

"Every week participants have to prepare a weekly activity report of presumed valid activity and fill up Weekly report form, not reporting within the next week leads to renouncing the prize for that week."

Does it mean I would have to post a list, here, of every Bitcointalk thread post I make, in a similar way to what the Twitter and Facebook participants have to do ?

..also, the sign-up form has the section  "Do you want to earn extra stakes by wearing the AllSporter 3D rotating Avatar?", from where do I get this rotating avatar, I see no link to it in the OP ?
