If you try using some of my software, or any software come to think of it, and it doesn't work, or causes you problems then there is a simple solution.
Tell me. I might not be able to fix it immediately, I might not ever be able to fix it. But chances are I can, and if there is a record it'll help others out in the future regardless.
I've bumped into this in the past "Oh yes I tried to use that tool you wrote but it didn't work, so I ended up with something else."
