URL profile format, which looks best...?
 

http://profile.mydomainname.com/UserName , http://mydomainname.com/user/UserName or keep the current http://mydomainname.com/view/UserName.html

i'm going to use a mod rewrite, if a different address is suggested.

username.mydomain.com or mydomain.com/username are the best, but out of your options it hard to pick one thats better than another.

i like the compact sub-domain profile.mydomainname.com

:D

3rd variant is pretty
