Impress Addons Site

Hello again:

I am working on a big project. I am very interested in using ImpressCMS for it. It requires a whole bunch of stuff, and the customer is willing to pay for custom module development (I'm sure I'll inquire about it later).

One of the features is that the site should be available in a few languages. However, he had some kind of web navigation and communication guru that wants to have a specific message, stated specifically in certain way, and in a specific part of the pages. He gave me a spill on eyetracking web navigation research, or something like that, as a way to explain the importance of having certain things stated in a specific way in a specific part of each web page.

Aside from the default core language features in Impress, I tried to follow the multilanguage tutorial here in order to integrate multilanguage in the theme. It gave me an error (related to smarty is my guess). It's the tutorial in the wiki.

Is there anyone that could give me a pointer on how to use smarty in a theme for multilanguage?

Also, since I don't want to be a taker, once I learn how to do that, I want to volunteer correcting and updating that wiki entry since it didn't work, maybe I can improve it, but I need to know how to actually work with it.

Any help? And if there's another tutorial or pointer on multilanguage, that'll be great.

I want to be able to create my own set of language variables in addition to what the modules and core provide. I understand I can do that with smarty.
