In response to the ongoing calls for a facility for wiki-like store for internal documentation, I've set up a documentation section on this site. It offers tree-structured pages, and they may be written in either HTML or LaTeX formatting. Images are best included by first adding the image to the site, and then using the add image link below the text box, or the control within the rich editor.
Pages should be associated with specific projects, but currently those project nodes won't be created automatically. Instead it is necessary to first create a documentation page relating to the project (with no parent). By convention, that name would be the same as the name of the project entry. When the site undergoes migration to Drupal 6, this should become more automatic.
Currently, image embedding probably won't work on
entered pages. If this becomes something that is desired and doesn't work, contact me or file a bug against it.
