Tom Khabaza, Email Voting Confirmation
I'm very pleased to see this confirmation system in place. I think it will help us get more accurate results.

Katharina Morik, free system
Yale is well suited if feature extraction and selection is necessary. Its storage of long data mining chains allows re-use for similar cases.

Paul Pimenidis, I missed Yale...
I missed Yale (http://yale.cs.uni-dortmund.de) in this poll. This free environment adds much value to Weka and seems to have a huge number of users.
