Ouch.. After several trials and errors I finally managed to link my portfolio. There are several numbers you might think to use, only one work as intended.

So you have to look the line http://www.cutcaster.com/search/portfolio/xxxxxxxxx/ on your CC referral page like John said.
That last xxxxxxxxx is the number you should insert on your MSG profile field, not your code (actually it is you code, but only the last part of it) and not the number in URL that appears on your browser's address bar.

That URL confused me because it will change when you paste it in address bar and hit Enter.
Hope this helps someone as stupid as me.
