Two things:
1) Having an "LTR Forum" might encourage AFCs to continue trying to "make things work" in hopeless or damaging situations. Could do more harm than good.
2) I don't really see how the techniques and attitudes used to KEEP a woman should be any different than those used to GET a woman.
I'm not a big fan of the misconception that once a guy and girl are "steady" (or even MARRIED for that matter), the dynamic of the relationship needs to change. Personally, I think it's why lots of couples that are happy when dating end up getting divorced once they get married.
