Phorum is one of the open source web discussion systems that we have customised for D3E, selectable from within the Publisher's Toolkit. D3E-Phorum is the most recent discussion system we have worked on, and the one that we are most likely to continue developing. Its features are more sophisticated than D3E-HyperNews, and we recommend that you adopt this.
See the demonstration article for an example of a document using D3E-Phorum (where you can post test comments).D3E-Phorum features:
Software: known to run on the Apache web server and Microsoft's Internet Information Server (IIS); written in PHP; uses MySQL database
Hardware Platform:Windows 9x/ME/NT/2000, or Unix/Linux (for an alternative unix web server discussion environment see D3E-HyperNews)
