Do not ask too many questions in one thread. Do not ask more than two questions in a post. And do not tag new questions onto a thread that have nothing to do with the original question (follow-up questions are OK). Otherwise the thread gets convoluted and difficult to follow. It is better for forum organization and better for you to get your questions answered in a more timely manner if you start new threads as necessary for remaining questions. eg. If you have five questions, post two of them in two threads and start a new thread for the remaining one etc. And if the question has more than two parts to it, it is best to post only that question and its parts in the thread and start a new thread for other questions.
Show some effort.If you want help with a question it is expected that you will show some effort. Effort might include showing your working, taking the time to learn how to typeset equations using latex (there is an entire subforum devoted to this), formatting your question so that it is more easily understood, using effective post titles and posting in the appropriate subforum, making a genuine attempt to understand the help that is given before asking for more help and learning from previous questions asked. Moderators reserve the right to Close threads in cases where the member is not making a genuine effort (particularly if the member is spamming the forums with multiple questions of exactly the same type). It should also be remembered that all contributors to MHF are unpaid volunteers and are under no obligation to answer a question.
