You need to contact the administrator to change your bate of birth - his user name is fluffy, you can email him by clicking on 'Community' at the top and selecting members list search for Fluffy, then you can email him by clicking on the 'contact' tab. Hope that this makes sense.
As for kiwi's pictures you can start a new thread under what breed of hamster he his, or in 'hamster chat'. I will look forward to seeing them!
