We also keep a list of open problems and of upcoming events. The wiki has an assumed bias towards regularity results and consequently to equations for which some regularization occurs. But we also include some topics which are tangentially related, or even completely unrelated, to regularity. Some answers, including how to participate, can be found in the section about frequently asked questions.
