Well I will have to start doing that then. :)

Good to know.

Great, looks like I will need to allocate additional time for that as
well. :)

I do plan to purchase the CD or better yet a subscription. I assume the
subscription last for a year. So I will need to add them to out yearly

I just have some other software and hardware that needs to be purchased
first. Then I will make the purchase. As it looks like I will need to
make the purchases as a Corporate buyer.

The curve can be great at times, but the more docs, the better. At least
they can be used as references as all the pieces in the puzzle start to
come together.

Or at least doing my best to acquire what I can.

No way would I take it personal. I can imagine the time it takes to make
things like a DB engine and etc. Much less going back through and making
thorough documentation on your work. Also in the process breaking down
some what complex issues so us little brains out there can understand
what the genius have built, and what we can do with it.

All for free, just so others can benefit and profit off your work.

So I will do my best to contribute my part, or my cash. So that the work
is not being done in vain, but more importantly so work can continue to
take place.

As I am I am sure many other appreciate it and will be using it.

Plus with the docs and etc, I will have a better advantage over others
who do not have them. Which hopefully will help me make the right
