I have been employed exclusively in validating instances of EtQ since October of 2002. As a result, I am somewhat familiar with their web site. The forums listed in the link are really just conventions at which they have a sales booth.
I may have accidently been misleading with my reference to it being a QA tool. I did not mean for use in software development or testing. It is used by QA departments for manufacturing process and product related activities. Sorry about that.
