What exactly is the difference between the full version of Cortex Command and the free version?

Full version has unlimited skirmish time, and the editors.
Support version is exactly like registered.

As of now, that's all the difference.

In build 19, unregistered didn't load mods, and skirmish demo time was only 5 minutes.


Later on, registration will unlock the full campaign, while unregistered will probably only have a mission or two.
Still gone, for the record.

Okay, thanks for clearing that up for me!
