After a month of contemplation and considerations regarding the time and effort one spends implementing a KB solution for the longer term; I decided to give Eniston a try. For all things basic and necessary for a KB solution it is superb and practical to get started with right away.
Mobile app would be excellent for edits and updates of KBs on the go.

For viewing; the mobile responsiveness is ok for now but becomes a bit challenging when their are links in articles

Folder and article level sharing permissions would make this tool amazing ie for users added to platform.

Thanks for investing your time and also stating your commitment to keeping this solution alive for the longer term. This is very important for users like me who need to use my KB on a daily basis and for the longer term.
