New to db4o? Learn & Have Fun!

I just wanted to point you to a series of funny (comic style) db4o blog posts by gamlerhart which make a great way to get you started with db4o (why not having some fun while you're learning?). I think the blog posts also deal with key issues that you must have in mind if you're new to db4o (Activation- & Update-Depth, Object-Identity and High-Level-Caching, Transactions, Persistent Classes Tips and Single Object-Container Concurrency)
