Maybe it's just me, but I find it highly irritating when a poster double or triple posts problems in the HW forums (and sometimes HW plus Gen Math/Gen Physics). Not only is it wasteful of bandwidth, it makes a mockery of people who take the time to answer the question and format the answer nicely, only to find that someone else has long answered the question in the duplicate post. It also takes time away from answering the genuine questions of other people patient enough not to post it to a hundred different places. It would be nice if the Mentors could make a bigger issue of this than is currently the case. A proscription against multiple posts should be included in the sticky in every forum (including an explanation of why it's not considerate to double post because some people may just be too thick to realise it on their own). Maybe also make every poster sign this as part of the agreement before posting in the HW forum. And people who persist in double posting should be warned, with the incorrigible ones being banned. I know mistakes can happen when the poster initially posts in the wrong forum, but the considerate ones *always* post an apologetic note to the wrong thread so noone will waste their time there. I really hope something can be done about this problem.
