Can ListMessenger be multi-lingual at all?

The ListMessenger program interface can not be multi-lingual as the program in it's current state was not designed for this; however, a future version of ListMessenger may support this (this feature has been talked about, but has not yet reached planning stages).

The End-User tools (IE, the part of ListMessenger that the end-user would use, like the sign-up messages and what-not) as of 1.0 are multi-lingual capable and use language files that are located in the public/languages directory.
