Truth Social review: Group

I set up a "group" called Conservative Friends. I know how to allow others to join but that's about it.
Does the word Truth mean Post? How do we post to all members at one time? How does one member post to less members than all members?
I can see why you are not growing. You make this VERY difficult to use. I have only allowed 8 members but they are all confused as to how to use it.
Please send me a "set of instructions" or they will get frustrated and go back to X.
