Sedo keyword optimisation problems

[opalxx]

i must confess i am pretty new to this and am battling with sedo. I have loaded a few domains to sedo for parking...most are adult names...anyway when you park a domain sedo automatically loads default keywords to optimise for some domains that reflect (supposedly) your domain name meaning...but of course some are a bit off the mark and when i attempt to change the keyword to something more meaningful it is rejected. How do i get over this..i.e for mobilemassge.mobi sedo keyword is NUDE which has little relevence, for boobyprizes.com sedo keywords are booby prizes, for diggout.com sedo keywords are digg out and lesbiansexmodels sedo bunged in lesbian EX models etc etc...bit pathetic really. Are other parking sites more user friendly...seems pointless parking domains if the keywords don't reflect what the domain is...
