- https://secondrenaissance.net/art/magazine - fix issue 2 of magazine still accepting submissions - DONE
- https://secondrenaissance.net/about remove job descriptions for individuals - PR raised

- https://secondrenaissance.net/oasis removed unnecessary descriptions of how events used to be structured-PR Raised
- https://secondrenaissance.net/publications/overview-ecosystem-names#metacrisis added link to [metacrisis.info](http://metacrisis.info/) - DONE

Following changes are proposed as priorities:

- [ ] https://secondrenaissance.net/papers add other white papers in a section at the bottom called ‘other white papers’.
- [ ] https://secondrenaissance.net/glossary tidy up - move ‘overview’ links to main list. Amend ‘how to contribute section, removing references to wiki and github’

Start with the /papers and /glossary pages named in the issue and inspect how their current content is organized. Add the other white papers section, move glossary overview links into the main list, and remove the specified wiki and GitHub references; verify both pages reflect all requested changes.
