I got an email from onlinereminder.org, where I could renew it.
They give you a credit card form to fill out, and for only $79 I can renew my domain for a whole year!
Gee, if I renew it through my own host, it's only $9...
I highly doubt they even renew it for $79, they likely bill you and do who knows what with your cc info.
The link they supply goes to http://www.domainrenewal-online.org/, the email claims to be sent from renewal@onlinereminder.org however, any messages sent to that addy fail to go through:
81.198.161.170 does not like recipient. Remote host said: 550 Unknown user Giving up on 81.198.161.170.
There is no info on google about this organisation when I try to see if anyone else encountered them.
