Wiki Pages provide a collaborative space for sharing knowledge related to a Project.
Each project can have its own Wiki pages that are by default viewable only by Users who are invited to that Project or have access to this project.
This makes it the perfect tool for sharing the initial brief & specification, meeting notes and client feedback sessions and building a knowledge base for a particular project.
Furthermore, more granular permissions can be used to control access to particular pages. This can enable secure sharing of account details and passwords between your team – or even between your team and external suppliers or vendors.
