Readers ask me for help with AutoCAD and I do my best, even though I am under no obligation. After all, I'm not being paid $4000 a copy. I'm used to rarely receiving thanks for the help, so it was nice to hear back from Mike Kaluski: Thank you very much Ralph!!!
For the first time ever, I got a negative thankyou last week. RH asked for some help with a Release 14 problem. After I suggested a solution, he wrote back: "IF YOU HAD TOLD ME TO 'GO HANG BY YOUR THUMBS' IT WOULD HAVE SAVED YOU SOME OF YOUR VERY VALUABLE TIME."
I feel like billing him for my time.
