Just starting - looking simple examples

Hello everyone

I've just come across RapidMainer thanks to a colleague.

I'm new to data mining and I'd like to know if there are very simple exercises or examples somewhere that I could start with to help me comprehend this software and some of its features?  Several simple case studies that explain some of the processes and concepts would help me greatly in understanding what I could do with this software.

Any help or suggestions would be appreciated.
