I've decided to be "Robby" throughout the one laptop per child (olpc) online community -- using the nickname that served me well when my hands were as small as those the little green xo computer is intended for.

Here's Robby's olpc bio page, with links to olpc forums, wiki pages and interesting projects -- including the idea of adapting a journalism tutorial originally written for senior citizens with pens and 1990s' computers to one for children with little green 21st Century laptops.
