ThomasAH, I agree.

The HTML required class is assigned to exactly the fields you describe.
It looks like a css entry for required is needed. I think:

.required:before {
    content: "*";
    color: red;
    font-weight: bold;
}

to add a red * before required fields should handle this. I can also We 
do have people using the orignzsation field I think (that was the cause 
of the "can't change myuser profile" bug a while back). I think 
removing the phone number makes sense.

Surprisingly I found one of my previous co-workers is registered
on the tracker and has used the phone number 8-).

Dannio, do you think this would solve your issue?
