Carlos,

snip-snip "My inputs to any thread in the SI list are basically
unbiased."

I think you need to re-read your initial letter....It looks pretty biased to
me. Especially when we keep in mind that you have a financial stake in your
position!

there are plenty of AEs out there representing other tools who restrained
themselves after your first e-mail, I applaud them.

best regards,
Jim

Ken:

It looks like you may had a bad experience with one of your tool
vendors!!... My inputs to any thread in the SI list are basically
unbiased. I am a not a sales person and by know means promote the sales of
our solution on this list.

If you are unhappy at my post, then you should address this to me
personally and not to the entire SI list. As tool vendors we are out
there to help you and everyone else, and I/we certainly get useful data as
what direction and technology enhancements we need to incorporate into our
tools or what typical problems are warranting attention from users such as
yourself or the folks of the SI list.

You will get biased opinions from the users on this list as to which tool
vendor works best, and that's great. However, I encourage that any
negative comments or problems that are associated with your tool vendor are
addressed to the tool vendor or your support person directly, not the SI
list.

Any comments you can email me directly and I will send you my phone number
and discuss any technical issues or just to answer all of you questions.
