oy.lc is a generic SLD (Second-Level Domain) created and administered by Changaco.
"oy.lc" isn't really supposed to mean anything, if you were wondering.
I haven't put in place an automated system for the registration and configuration of oy.lc subdomains, but you can send your requests by email to changaco at changaco.oy.lc.
When requesting a new domain, please include a brief explanation of what it will be used for.
