That's a good question. It could be a coincidence of names. The "East European Christian Correspondence Center (EECCC)" is also the name of The Family International's "unit" in Hungary. It is the location (or, at least, was) of where they translated all of their propaganda (or, literature) into the local languages in the Central and Eastern European languages. It used to be located in Leányfalu, Hungary (just north of Budapest). It was referred to, internally, as the "MM Home".

After looking over the URL you posted, I am not sure that there is any connection with TFI.

There's another link that's defective on the article about Charles Luis Allen. Apparently, Lamatteryresource.com is no longer up and running as a website.
