A-I-M, interesting. Do you have their exact corp name or better yet a phone number? Could it be a different Penson? I spoke to Penson Financial (aka Penson Worldwide) web penson.com.
Also to JB, just for sh*ts and giggles I contacted American Registrar and Transfer Co. and they are not a TA for EFGO/MONA/GLCC. So they aren't part of this.
