Elements which are not listed as features and are strengths of PmWiki :

  • Small code base (under 2 MB)
  • Many parameters are handled by pages, without having the need to open system files, which greatly helps the Wiki administration.
  • While there is only one major developer, there is a very active community and most addons are from independent people.

Add a new feature you would like to see in PmWiki as a new PITS? entry marked Feature Request, or use one of the mailing lists to brainstorm new features.
