a subdomain is an extension of another domain like mish.pupusas.cc ("pupusas.cc" is the domain and "mish" is the subdomain) you can use subdomains from us just like normal domains without having to go out and buy them contact valasztas[at]keemail.me to request a subdomain to make it easier to read through, you could write your email as something like this (not required, but encouraged): "i would like the subdomain (your choice here) on pupusas.cc. i'd use this subdomain for (your reason here), and i would want it pointed to (your records here). i swear in good faith that i will not use this subdomain for malicious or illegal purposes." as a reminder, these are free to use but we'll accept donations if you want to support the costs.
