Ya know, there's a REALLY easy way that always worked for me. Click on the glasses icon (so you can view your own rig) then just copy the url at the top of the page.
Automatically has the "rigid" in it, and should work. Then (at least I think) you wont have to take all those 10 seconds of your life fixing it typing "rigid=" (and everything else) in.
Edit:
And I never use the rig id that myanandtech generates for me since thats the bad one. I just use what i got above.
Does this not work for anyone? Cause it seems like the easiest method (of all the other easy methods )
