It seems early to be thinking about this, but submissions are open for the Eastern APA. (You have some time yet to get your papers ready if you haven't.) I had a bit of trouble finding the page I needed to submit my submission, so my advice is to head straight to the member log in section (here). From there, look to the bottom of the page and you'll see the right link to follow under "Online Resources". For some reason, the links the APA provided with the announcement that submissions were open took me nowhere useful.
Hope this helps.
