I would like to give you an example, I noticed a thread "Charity V State" There is a comment about a sperm bank ( I thought it was funny ). But is it a suitable post for a forum where children could see ? and is it a good comment for the subject ?
It has been viewed by two mods who have posted on that thread, but no comment has been made about the post, I expected it to have been deleted today because someone would have found it offensive or not suitable for the topic !
If you had an opt in board the post could have been edited by the mods team, and a message left saying (this type of comment should be reserved for the opt in board).
Or maybe the person who started the thread would want to put it in the opt in board to create a more heated debate.
I think I do Fred.
Maybe a serious chat/debate board, sub board 
Will need some thought

Yes.
S.J, I am not saying make it a free for all, I just think if there was another type of chat board we would keep more members. ( I repeat again I am not asking for changes in forum rules ).
Roger, I understand what the forum exists for and it does a very good job, and no it has not failed if a person gets help. There is a chit chat board for a reason it keeps people on the forum, the more people on the forum the friendlier it becomes.
JoanJ i agree the mods do a good job and the forum is a great help to people, i would just like to find a way of keeping members.
Last night there was 138 Guests & 28 Members on line. wouldn't it be better the other way around.
With an opt in board i feel you would keep more members, I still find the post about the sperm bank funny, but i wouldn't feel to happy reading the post with my children ( if i had any ).
The opt in board would give that member a chance to make that sort of comment, and enjoy the forum more, if you enjoy the forum you stay, if you stay you help others.
We are a community of people with a common problem, but we don't all have the same views or sense of humor.
