Just came across a blog which is documenting the experience of writing a Redbook on Domino Web Access 7 at ITSO in Cambridge, MA.
I spent one of the best five weeks of my career with IBM working on the Migrating to Message Broker v5 book back in spring/summer 2003. I got to spend that time working with a group of 7 hugely talented people from around the world (Australia, Japan, South Africa, US, UK), plus it gave me long enough working in the lab to finally work out how to find my way around IBM Hursley!
Our Redbook Residencies are open to customers as well as Business Partners and IBM employees, so take a look at the list of upcoming residencies and see if there is anything you'd like to get involved with. It's a very rewarding experience.
