Creating new maps is easy and you simply add your thoughts as they come to mind. As well as storing your mind maps online, you can also export them in various mind map formats (or even as a document outline or image file). And, you can also import existing mind maps into MindMeister.
'Widget Mania' is an example of one that Mike created and invited me to join in. Great fun and this one is not finished yet!
Here's one I made myself as part of my online course that I am completing at the moment.
