Multimac by Silverlit

That is a shame, I too am new and it had just occurred to me that this site might be useful for tracking down and checking off multimac toys.
What is the definition of action figure the site is working on, so I can better understand what not to expect to be able to find here? I've seen a few statues and gamepieces in the DC and Marvel selection and those don't really fit what I would assume to be action figures, so I suspect my assumptions about the term and the working definition for here may not be the same.

If you don't find a toy line in the Checklists we have, you can request from Captain Coder to add them and he'll try to find the info. You can find the "Contact Us" link by clicking through any of the topics in the Help section.

You could start the search for more info here maybe - http://www.collectiondx.com/toy_review/1987/treadmaster

Looking at that toy line, that's more like a construction set than action figures, so probably not going to be in the checklist here.
