To Tabby: you don't have to wait for a new one. you can jump into any of the Blocks of the Month we have going already. the BsOM are explained in the blue topics at the top of this page:
http://www.quiltingboard.com/forums/show/9.page
if you would like to get on the list for a turn to select a block for us, send me a pm. i'm starting the list for the blocks we'll post on the 1st of each month in 2010.
I don't think Shadow Dancer has selected a theme yet for the blocks to be posted on the 15th of each month. interested parties should drop her a line.
To gramqlts: i just sent you a pm.
