[OLPC-AU] New member saying hi

Thu Oct 14 18:26:55 EDT 2010

Hi Peter, just wanted to make you welcome - and invite you down the road to Sippy Downs on the Sunshine Coast. Was speaking to Peter and Sandra just yesterday who were telling us about your activity - and now I've been able to read about it courtesy of your blog! BTW, would love an rss on your blog so I can follow new entries.

Ok, hope to meet up soon - how does the last week of October sound?
