This article isn't officially released on SSCentral yet, I need to do some changes to the site to make the list stuff look like it's supposed to (with CSS) and I haven't made pictures for the article yet. I thought it would be nice to put something up as a teaser for what's to come, lots of new tech articles, mods and even a few homemades.

I have several more articles planned for the Tech Articles section, of course including one of additives. Keep a watch out in the next month for the updates.
