Brian,
Using the search function will give you access to what by now is more than 7 years of hard won data and considered opinion on the TDI series. I was offering what I considered to be the best advice I could give.
You did nothing wrong by posting - and neither did I by responding. I apologize if my tone was a bit stiff, but I think you will find that on most forums, folks appreciate it if requests for basic information are made after some effort work is done to see if the information has already been contributed before.
Someone like Reg Sniff could probably sit down and use 20 or 30 minutes to compose a thoughtul and authoratative response to your post, but since he has already spent endless hours doing just that in previous posts about the TDI platform over the last 7 or 8 years, he might not feel much like doing it all over again (that, of course, is up to him).
And to CP, i think if you have a look at some of the 538 posts I have put up during my 7 years on this forum, you will find that I have generally posted thoughtful and often informative stuff. It's all well and good to RECEIVE information and help, but it's also good to GIVE some also. Writing even a simple post can take me a good 20 minutes if it has any useful information in it. You can have a look at my recent post in the "Spanish Pieces of Eight" thread in the Whites TDI Classroom Forum for an example, that took about 20 minutes to put together.
Suggesting that someone who wants basic information do some homework on the Forums to harvest the gems of information that are lying there for the taking, is in fact excellent and I believe valuable advice.
My tone, however, left a lot to be desired. For that, I apologize again.
