If you go here: http://www.caves.org/imo/frames1.htm
You'll see a graphic that says, "Big News from IMO." Click on it and a PDF loads up that says, Alex is retireing and Jeff and Nina Martin of GA are taking over.
Truely the end of an era. Alex will be missed. Congrats on the retirement tho!
Congrats to the Martin's too! Should be a fun job.
