[Dimitris Kotzinos]

Hi Landon,

I have uploaded the Greek Chapter annual report for 2011 here (following 
your template):

Please let me know whether you need any changes/corrections or it is OK.
Also depending on your scheduling I might also be able to help putting 
together the next journal so please update as needed.

Best,

Dimitris
