Most pages in this Wiki have a Discussion tab along the top, where users can enter comments. Please use this feature to discuss the content of a particular page.

There is also a separate list of changes we intend to make. This list includes both technical changes (fix typos, add diagrams, etc.) and conceptual changes (e.g. add more problems). If you wish to add items to this list, please use the Discussion tab on that page, rather than on the actual page you are referring to.

If you use this mechanism to provide feedback, you can use the breadcrumbs near the top of the page to tell us which page you are referring to. If you hold your mouse over any item in the “Trace” box, a message should pop up with the Wiki path to the corresponding file. Simply copy this path into your comment. (If you put the whole thing in double square brackets, you will create an automatic link to the page. For example, this page is feedback, entered as [[wiki:feedback]].)
