If you wish to have a private chat group here, let me know and I will set it up for you.
I set up the group, make you the “owner” of that group, and then you can invite whomever you want. Groups can have more than one owner.
Then I set up a “Sub-Category” in the Private Groups Category that only your group can access. It’s like a mini-forum. You can have as many topics as you like or just one long one - it’s up to you.
Mods are supposed to be able to see all Categories including Private ones. Currently only Admin can see them and I’m not sure why that is - but I am not making an effort to change that right now.
The Private Sub-Categories are set up to where only group members can see the posts. But being that this forum software is new to me, I’d proceed with caution and know that nothing on the internet is ever truly secure.
