like gunther.sf.net does - nah, too much of a security issue. A recipe for that is easy to implement... but who would be crazy enough to do it? ;)

Could be done, once we figure out how to control the caching; probably a set of recipes for specific types of wikis
E-mail notification by page
Easy: just enable Notify in the local/config of the page(s) you want to monitor.
Interactive table editor
If that means WYSIWYG-style editors, pmwiki's not the answer. At least currently.

Elements which are not listed as features and are a strength of PmWiki :

  • Small code base (under 1 MB)
  • A lot of 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.
