uhmmm.. the code appears to work fine but it in fact don't not works the way I wish

In fact, it don't add avatar for users, just edit these templates: postbit, meminfo. How could I know that? In member list, their avatars is not showed!
BigJohnny, you are a coder, right? I'm not, so although I tried to look for the code of adding avatar for member in modifyavatar template, but couldn't make out what that code is.
I think that code is not too complicated. Just put the noavatar.gif with a radio button below at the registration template, so when user click "Complete registration", they have a avatar IN FACT.
John, could u please..
