I've tried to add a Zone Record for the domain tycho.is as the first step before mapping the domain to my wordpress blog (tychosisland.wordpress.com).
The DNS Zone Records page (http://en.support.wordpress.com/domains/dns-zone-records/) returned an error message ("We cannot add a zone for the domain you've specified. Please contact support for help.") and asked me to contact support.
Could you please add the Zone Record for me?
