Can an Evangelist not be Invincible

A good question. No, an excellent question.
Sometimes you venture out beyond your scope of knowledge, for clients.
And when you go asking for information you sound like a jr. tech geek.
But I will always be the first one to say "I don't know" when I don't. I learned enough to know when to reach for help, rather than make something up for clients.

Such is the case I find myself while asking the very knowledgeable Nathan of OpenNTF.org fame. My appdev knowledge died years ago, around the same time Windows enabled databases.
So I needed some help with a DB2 integration question for R7 and he gave me an answer which was concise and to the point and even financially astute(licensing costs).

It's a great thing to be able to contact people who can help you, true evangelists.

So while the answer is not definitive, my client is sending me more details on their request, it does help me to understand some basic issues which in my head down admin path I forgot.

My bad.

On a lighter note, I proved the IRS wrong in billing me for some corporate taxes which were paid, yet they did not properly code them. All in a day's work.
