Please update AIMCO

I meet Mr. R. E. Romo maker of the ss Luger at the gun show sat. He ask me to update the Links & Resources with the new phone number 713-617-0474. The Fax is the same. He also has a e-mail which is RAMROMO@EV1.NET. I am unsure who I need to contact to have the change made. Please advise.
