Warning - The Domain Registry of America - They will try and trick you

If you own your own domain name then you need to be on your toes when it come to these guys. They are called ’The Domain Registry of America’ or DROA.
Sooner or later you will receive, via the post (snail mail) a very convincing renewal reminder for your domain, regardless of where you domain is actually registered, they don’t care, they just want your money.On the bottom of this letter will be a payment slip suggesting that if you send them payment they will renew your domain, however/but - unless your domain is registered with the ‘Domain Registry of America’ they cannot actually renew it, only your current registrar can do this, in this case they will request that the domain is transferred to them so they can renew it.
Court judgements have been served on DROA, read more here and here, in fact if you search google you will find loads of complaints about this company and their ‘domain slamming’ con.
If you do get a renewal letter from DROA, recyle it, do not pay them anything else you risk loosing your domain.
