You can give it a try asking in other post 2 host forums like nationserver.us, I'm not quite sure if they also offer domain.

There isn't any post2host forums that provide free domains at the moment, however, I guess you should try .eu.org as others said, or go for a sub domain, it's really hard to find a gTLD (global top level domain) (.com .net .info .org, etc) for free, maybe you might find a ccTLD (country code top level domain) (.tk .in .ml .ga .gq .cf, list goes on)
