If you have a problem while proofreading a page and canotcannot finish it, you can set the page status to "Problematic" (blue). This will alert other people that a problem exists, which they may be able to solve.
CommonsCommon problems include pages with illustrations (if no image file is available), pages with equations, pages with foreign text (especially text that does not use the Roman alphabet) and pages with special formatting. In some of these cases, special templates exist to identify the problem (see [[#Problem templates|Problem templates]], below). These are useful to anyone else looking at the page and they can attract the attention of people able to fix the problem.
