Hi Zchi,
I checked into it about a month ago, because I heard of it from some other locals, and other national groups. But from what they told me, and what I gathered on the site, it's open to ALL orgs. I believe it takes place in February , and it has a bunch of workshops, and awards, and u meet other greeks, yada yada. But it's supposed to be very helpful and fun,etc.. I know a few locals went though. DGP is going to go this yr. Heres the website if you guys want to check it out.
