I dip into and out of this forum depending on the level of 'help' on offer. A hint is what I call help. Providing answers is not help. Just as only a foolish schoolteacher would set a test and immediately tell the class all the answers so I do not expect solvers to do the same.
Even though many people do not enter their solution into the prize draw the satisfaction is getting the answers, preferably on one's own, but coming to this site for some helpful nudges.
There is another site - Answerbank - where answers are freely given and accepted.
