The posters should be 12"x18"
(allow an 1/4" bleed allowance if you want your design to go full bleed to the edges -- e.g. make it 12.5"x18.5" final size, but keep your text/images/etc. within the 12"x18" size)
Should be 300 dpi (though you may want to size down for uploading here... not quite sure how big we can handle).
Previews here can be RGB, but the final poster should be either created or converted to CMYK.
I think that's it for technical details.
