3. Telepark Wiki
   
   telepark.wiki is the first Wiki software to offer a tree-type hierarchical navigation to keep one's wiki organized and easy to use. The number of levels in the navigation tree can be limited artificially (e.g. to 3 levels) by way of configuration or can be unlimited. In addition to this in-built navigation, each page can contain any number of links to other pages for non-linear navigation. Links are created using telepark.wiki's visual editor. You can allow anyone to edit your wiki or require a password. It is available as a free Standard Edition and as a Professional Edition for 99 Euro.

4. Syncura
   
   Syncura is a team solution for document collaboration designed to save you time. Syncura makes document sharing and collaboration as simple as saving a file to a shared folder. It's like a virtual network folder without storing files on a server. Synchronize folders with colleagues and clients, or just keep all your computers in sync. The amount of data you can share is only limited by the size of your hard drive.
