E-mail notification: Get automatically notified when something has changed in a TWiki web.
Structured content: Use TWikiForms to classify and categorize unstructured web pages and to create simple workflow systems.
File attachments:Upload and download any file as an attachment to a page by using your browser. This is similar to file attachments in an e-mail, but it happens on web pages.
Revision control: All changes to pages and attachments are tracked. Retrieve previous page revisions; compare differences; find out who changed what and when.
Access control: Define groups and impose fine-grained read and write access restrictions based on groups and users.
Variables: Use variables to dynamically compose your pages. This allows you for example to dynamically build a table of contents, include other pages, or show a search result embedded in a page.
TWiki plugins: Easily install program enhancements using external plug-in modules. Developers can create plug-ins in Perl using the TWiki Plugin API.
Templates and skins: A flexible templating system separates program logic and presentation. Skins overwrite template headers and footers; page content is unaffected.
Managing pages: Individual pages can be renamed, moved and deleted through the browser.
