On another Web Forum I go to,the following options are available:~
1.You can block a person from seeing any of your questions ,and therefore answering them.(other members can see and answer in the usual way)
2.When you answer a question, you can block a particular person(as above), so that you cannot see their answers to this question.
These 2 options are used together.
I realise that the above may not be necessary(or wanted) here ,but I thought I would just let you know what happens on other forums, to prevent trouble/problems
That sounds more like a private messaging service than a forum.
A 'forum' is intended to be open to all members or there is no point in it. What is the name of this 'forum'?
I *think* it was tried on here...briefly...back in the very bad old days of AB. It didn't work. While there are squabbles on here,it's usually quite tame.
