This is a container page that serves to add temporarily new projects while waiting to have its own page. If you find a project that you consider that should be on this WikiMathCom, but you don't have time now to investigate more or to write an article, you can just add it to the list below with a link or a reference to be checked later.
Items should not stay for long in this page. Sections are just to maintain a certain order, each article can be later assigned to one or more categories.
