Here are some guidelines when to use which tool:
Mailing lists
- All concrete information, like meeting requests, invitations etc. where you don’t expect an answer
- cloud links to documents you want to send around (see below)
Forum
- best for discussions
- questions and answers
- proposals & ideas where you expect (or would like) some feedback
Cloud
- texts you want to work on, proposal for meeting agenda,
- finished documents like meeting minutes, results, presentations,…
- you can create different kinds of links (e.g. read only, editing,…) for documents and folders
