A while back I signed up for MindMeister, apparently one of the best online mindmapping tools. Now I received an email saying that since I haven't logged on in a while, they want to give me some codes for two free months of premium service... No idea if anyone here uses MindMeister, but on the off chance, I have five (!) codes, each for two free months of premium, and am glad to give them out. Email me at verb, at principiadiscordia dot com, if you want one. (Only one per account, by the way.)
what exactly is it?
It's a website that lets you make mind-maps using a cool interface.
That you can do collaborative mind-maps seems like one of the coolest parts about it.
It's unfortunate that you have to pay to use it regularly though.
