add it in your profile with html myspace as added a redirect on all outbound links tho, so don't expect pr leakage from it.
The only way to get around the redirect is to have added the links b4 the change If you are being redirected to myspace it sounds like you might be forgetting to add the http:// ? like <a href="http://www.site.com">site name</a>
No, that no longer works in the profile. The links are changed automatically so no juice can be gotten anymoe.
