SL Dialogues is a companion resource for mods that need dialogues for relationships between the player and NPCs.   These mods all need to define NPCs as a dom, a sub, or a romantic interest in some kind. Instead of recreating the same dialogue trees again and again, Dialogues mod just defines a shared dialogue tree with a few parameters about the kind of NPC we are dealing with. That way, each mod can focus on unique dialogues and quests instead of recreating the same basic actions.
