Wiki can also be used for Managing Projects
Some of the features of Wiki used by my Client were :
1) Specific and clearly communicated location (wiki link) based on Project
2) Demarcated Roles and contact details of the team on the wiki
3) Calendar showing project deadlines, roadmaps
4) Minutes of the Meeting of past meetings
5) Past deliverable and its details in the form of presentations and Video
6) One place to get all the latest details about the project
Example : Daily deliverables, and Project status
Thus, reducing dependency on office laptop; by helping in getting access to details, documents, presentations independent of your location.
