I've seen this happened a few times in the HW help section. Someone asked a question, a few people spent a lot of time trying to give hints, guidance, etc. on how to solve the problem. And then, BAM, suddenly someone intervened and literally did the whole problem for this person. It happened again just recently: https://www.physicsforums.com/showthread.php?t=73674 I see Data and whozum patiently giving as much info as they can to help the OP in solving the problem. This tends to take more time and effort than simply just solving the damn problem for this person. Yet, all their efforts are simply washed away when someone comes in and did the problem for the OP. I know how frustrating this can be when all the efforts you've put in just went into nothing. Unfortunately, it is also not against any rules to solve the whole problem for anyone. However, is it possible to gently remind the "offender" that, if we go by Tom's Sticky in that section, that if one really wish to help someone, solving the problem for that person isn't the way to do it? I just feel that it undermines the whole spirit of the HW Help section, especially when we tell people that we're not here to do their homework problem for them. Zz.
