Hiya.

I think it's organization that's the problem. Maybe have two simple "Download A6 Stuff" and "Download A7 Stuff" links. Each one goes to a new page. On that page are three columns: "World Editor (WED) Tutorials", "Model editor (MED) Tutorials", and "Script Editor (SED) Tutorials". Under the Script Editor column, it's divided into three cells; "Lite-C", "C-Script", "Templates".

Now, each of those 'sections/cells' has download links to their appropriate tutorials.

Simple, organized and easy to update.
