to answer some of your questions,
you can update your country setting by clicking on the ‘profile’ link above. You don’t actually need your email account to log on once you have activated your acount, you just need your user name and password to log on from home or work.
You still can’t upload pictures to this forum at present but if you email some to me (via email@example.com) then i’ll put them on the website with any text you include.
If you want your username to be changed then let me know what you wnat it changed to and i’ll see if I can do it for you, the other option is for me to delete your account and then you can re-register with a new username ?
