Anyone know of any good and free concept mapping or mind mapping software?

Yes I know of one that I use, but its only a free trial. I think the trial lasts for 30 days or so.

I reckon its really easy and quick to use, especially using the shortcut keys like pressing 'insert' on your keyboard for a new branch, and you can switch around from branches using the arrow keys. Basically, its quick :)

Oh and having downloaded it and used it twice on two different computers, I can say that to my knowledge the software is safe and virus free.

Here's the website if you're interested:
