roberk - not quite. This is the "Trading Systems (Commercial) forum. Anyone who wants to post details on their commercially available trading systems can do so.
AFAIAA - DC2000 hasn't x-posted to any other forums - unlike the ET spam which was posted to 4 separate threads.
As for interested replies - only DC2000 has that data. He has asked for email indications of interest rather than cluttering up the board with them. Seems reasonable.
I'm not quite sure why you're posting an apparent response to a question that doesn't seem to have been asked "The difference between Elitetrader and trade2win?". Being that you're off topic in this forum, your post is even les entitled to be here than you thought DC2000's was.
Do you get my point?
As an aside, and in response to the question you implicitly asked by answering there are many differences between t2w and ET - the two that are most obvious to most t2w members are the signal:noise ratio and general quality.
And I almost forgot, the other is the quantity of sniping, whining and generally just plain negative for no particular reason posts ET get - t2w get some, but not that many in comparison.
