   Format: MarkdownItexStarted an entry on [[closed morphism|closed morphisms]], containing examples and characterizations using the internal language. Then I noticed that an entry on [[closed maps|closed map]] already exists, but at the moment the nLab is too slow for proper browsing and editing. Will finish later and maybe merge the entries.

   Format: MarkdownItexThanks! I have restarted the server. Now it responds again. Then I have qickly merged the entries. I kept _[[closed morphism]]_ and made _[[closed map]]_ a redirect to it.

   Thanks!

   Format: MarkdownItexThanks! I have added a few more links and touched the formatting ever so slightly. Also made _[[closed geometric morphism]]_ a redirect. (We have for instance also _[[open geometric morphism]]_.)
