It would be great if Dynadot could add an option to specify a custom WHOIS message. So when you go to My Account - Domains - Contact Records - edit, you can set a custom WHOIS message for each contact record.
Another registrar has implemented this option: http://blog.easydns.org/2010/05/25/add-a-custom-message-to-your-com-or-net-whois-records/
Please consider, it seems like a simple thing to do... Could be a really nice addition to differentiate Dynadot from the other registrars.
