i don't recomend url forwards from regitrars.
its a lot of work.
some of them plain do not support it
I recommend you either set dns to bodis on all registrars/domains then from bodis do url auto redirect... and skip parked pages (the onyl company that lets you do this)..
or do like me if you need the extra functionality of easily switching between park companies with 1 click of mouse, and set dns on all regfistrars to above.com....... then from there pick bodis... or whichever you need.
plus above.com has nice for sale landers too.. 10% comission plus escrow service with domains going to above.com registrar after sale so it gives you more fraud protection
