The domain is registered by Carol. The domain has recently been expired. Maybe they are going to use the http://www.relmholdingsinc.com/ officially, or maybe they'll extend the domain registration period and use http://www.relmholdings.com/ .
But I believe http://www.relmholdings.com one should be more ideal domain name than the first one, and from what I presume by seeing this domain getting expired, HCPC is ready to merge with RELM. Well, I could be wrong...
