Here's a thread from the fall. Looks like melmichigan coordinates an OE program. I believe you can start anytime, but I'd pm melmichigan or look at the oe online pages. You pay for 10 mos and can progress as needed. I believe it's k-7 curriculum... After that you would need to do the pricier option if you continued w epgy.
