To post some thoughts relavent to your questions, not necessarily in order-
b. They want the website to do their homework for them. [They may pass the assignment - but have they learnt anything??]
I agree that there are a number of homework assignments, but I don't necessarily agree that just because they're homework, that they should not be addressed. It depends on just how much the student has already done. Its a fine line between doing the homework, and helping with the homework. Did you, when you were an upperclassperson in school, do the homework for an underclassperson. But did you provide help to the underclassmen? Tek-Tips should be no different. Answer the question in the same manner that you would have as a senior if a freshman had come up to you and asked the same question. Did they learn anything? Who knows, that hard to say. On the one hand, your point is well taken, but on the other hand, have you learned anything from the answers that you've received to your questions? Again, I don't do their work for them, but providing guidance and help is reasonable.
c. They want the website to do their jobs for them. [No doubt telling their bosses - 'Look how good I am".]
In many ways, the answer is the same as the one above. Put yourself in the entry-level position, and in the supervisor position, and view the question from both perspectives. Tek-Tips is a resource, as are help files and manuals. One cannot fault someone for taking advantage of the resources at their disposal. After all, they did get the job done. One could argue that the employee is good because they used the available resources to get the job done. But again, I personally will not do the work for you, and neither should you. But if you approach each question with the attitude that you are the supervisor, and one of your junior-level associates has face-to-face asked you the same question, how would you answer it. I submit that you should answer it the same way here.
a. The questioner has not bothered himself/herself to analyse the problem. They have not tried to use the supplied help files or anything - just straight to the webite!
You're the supervisor, and your charge has asked the question - what's your answer.
Abuse of the Tek-Tips system is just as much a responsibility of all of us who answer and how we answer the questions as it is to those who ask. Good Luck
