What have you used for team collaboration for a small business, think tank or other entity?
I just started to work with a small company and we have chosen to start with Slack. It’s a cloud based mashup of a simplified private forum, IM and integration with other apps like Google docs or calendar, for ex.
Slack seems pretty good. Create different ‘Workspaces’ for entirely different projects or companies. Within the workspace create different ‘channels’ which are sort of like forum categories. Each entry in a channel is a thread and it can have discussion within at one level of nesting. There is IM chat or discussion between individuals or groups, extensive search capabilities.
Here are a few of such apps The Best Business Messaging Apps | PCMag
Here is Asana, another I have heard about. Seems more project management oriented. https://asana.com/guide
