Not sure if I understand correctly - you want to open sort of a sub-forum where only Palestinian supporters will be able to participate? How can that be done, does it mean anyone who supports Israel will not have access to that section of the forum?
On another forum where I am a member, we have a section only for people actually living in the ME that was not even visible on the general index page to members to whom that did not apply. It hasn't been in use for quite a while, but it still exists.
It would be meant to discuss what Palestinian supporter see as different options to bring an end to the conflict?
I agree with JayUK that the ad nauseam repetition of old arguments every time a new member joins the forum can be tedious and lead to forum fatigue in general.
Sorry, but I am really not sure I understand what you mean or how it would apply?
