There will be an expansion in forum categories in the future, though not a cross-over forum, as supporters can ask questions in PTSD forums, and vice versa, providing either party does just that, being to ask a perspective, not go into an area and start arguing or disagreeing on threads due to points of view.
This has been thought of and raised in prior years, tried even, and the end result was both sides bitching and fighting, which was counter productive.
As a result, it was decided that both sides have their own areas, with the other only going into them to ask questions / clarify points, etc, and NOT give general advice or such... unless playing extremely nice and not being argumentative with the other side.
