I have been excited about excel pivot tables for the last 10 years and I must say I have done a lot of stuff with them. 10 days ago I discovered RapidMiner because I was looking for a fast way to plot multiple histograms. I was BLOWN away!

So congrats on a great program!
My questions are:
Is there any way quickly refresh a repository?
Is there any way to edit the data in a repository?
Suggestion: The dictionary entries on each operators are nice. However, they are extremely theoretical and cruelly miss a few examples... On many occasions I would have saved many hours if I could have just seen an example to answer simple questions like "Should I put quotes here? Single quotes? Double quotes?" and so on.
Speaking of which a few examples available to check out that cover the major functions would also be very helpful.
You'll be seeing me around for sure and being able to ask questions will surely make the learning curve much more bearable.
