In some of the forums we require that you specify the level of discussion you'd like in your thread. These can be found in a drop-down box next to the text box where you enter the thread title. If you have little understanding of a subject, or don't wish to discuss things at a college-level, select "B". Select "I" if you are familiar with the topic or wish to discuss it at a level you would find as an undergrad student. Select "A" for advanced topics that you wish to discuss at a graduate level or above.
