Never done this before so need some advice.

I work with people who work in a very niche area across multiple sectors and we would like to create some type of confidential method to communicate and network.

It has to be secure.

I am obviously not interested in FB or LinkedIn but would like to find some way to interact as a group.

The members would only be invited and be pre-approved.

I don't want something like a WhatsApp group as I don't want any option to spam or annoy members

Does anyone have any good suggestions?

Many thanks

Edit: Thanks Jan for the sensible additional points.

We will only be exchanging text info.

At its peak it would probably be 100 members

I and some others could dedicate a small amount of time to admin for a forum and we could allocate money to a solution but it would pobably be easier not to.

    Welcome to the site. Can you add something about the nature and volume of the conversations? Do you anticipate long conversational threads (where you might benefit from a forum's threaded commenting), or will there be more "one-shot" messages and short conversations, and is this a few messages a week, a few messages a day, a hundred messages a day? – Monica Cellio Jul 10 at 21:53

If you don't want to host the "forum" yourself, you might consider using a Telegram group.

If you don't mind hosting it, there are all kinds of options you might consider:

  • IRC (may be too ephemeral)
  • forum software (there are many) behind some form of authentication
  • some kind of repository-aimed tool like GitLab
  • bug-tracking tools like Bugzilla or Trac
  • a wiki
  • some kind of CMS like Plone
  • some Google Docs -like thing such as ZoHo

Regardless of how you do it, though, keep in mind anyone may copy-paste or screenshot these "confidential" conversations out of your private environment.


Transfer your "secret" data at the end of a huge text file..

Most search indexers have a very low limit of how big a file they index.


My app also has an encryption function.. Pass the key back and forth along with the data.

All my text files can be appended into a large one for export in a flash.

The search features are fantastic as well..

All data; confidential or otherwise should be this easy and quick.
