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?
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.
