How do I change the anchor text for my users to login to their backend?

Right now the anchor text to the link that allows my users to login to their dashboard is "Profile" without the quotes. (it calls the profile.php file). I would like to change the anchor text for this to something like "click here to edit your blog" ,instead of "profile" but I can't find the file that generates this anchor text...(I probably just can't see for looking...I think I have opened and examined every php file in the whole MU site...)

For my users (hobby woodworkers, guitar builders and such) "profile" doesn't cut it. They need link text that tells them exactly what to do. Like: "click here to edit your blog.."

If somebody can point me to the right file, I would sure apreciate it.

Thanks, Christina
