My favorite site for EC help: http://theinfantpottytrainingsite.blogspot.com/
This EC site has some great forums and help but takes a little longer to navigate: http://tribalbaby.org/http:/tribalbaby.org/category/elimination-communication
This site is vast - you can find EC shops, you can buy used from other mothers in the forums, there is a ton to look at. I recommend only coming here when you have a bit of time on your hands to really get into it.
