Hi and welcome to the board! My DH is from Philly suburbs but now we live in California. Anyway, if it is anything like the RESOLVE programs out here, you will learn a ton and meet many people just like you as well as reputable adoption professionals in your area, adoptive parents, birthparents and adoptees. The sessions are so informative and the Q and A sessions to follow are very helpful. If there is a social hour/mixer that follows, you will be able to meet and greet and forge even more relationships. You will probably feel overwhelmed but with a much better idea of where to begin to explore the different paths if that's ultimately what you decide to do.
If I were you, I would glance at some basic adoption reading material beforehand so you have a little more informed base going into the conference. I always find that if I do a little research and become a bit more conversant before meeting with an RE (just a tried and true example) or an adoption atty, then I can take in more of the details they flood you with. Here is a good site that gives an overview of the adoption process jsut so you can familiarize yourself. There are links to lists of questions to ask agencies and lawyers too...
