I have been reading this board this morning, and I think I've gotten some of the acronyms straightened out (like, I think SD stands for School District and not Step-Daughter!). Others (OHI? ARD? SED?) are still a mystery, and I can't find a place where they are all listed for easy reference. The general FAQ has a good listing of abbreviations that includes relationships and disorders, but does not include any of the school-related ones.
