For my non-adult domain names I have previously used Registerfly.com on occassion.
They are basically up shit creek as you cannot renew or update domain information.
Here are some sites I will be using:
http://www.registerflies.com - Info on how bad Reg Fly is
http://pokerrouge.com/blog/other/reg...titanic-sinks/ - How to transfer out
http://www.downdoggy.com/rf/ - these guys are offering $1.99 transfers to help
Please note I am yet to try to transfer any domains out as they are not that important to me - as my porn domains (thank god for godaddy) - and therefore I have not tried down doggy yet too.
Hope this helps !
