I was reading GlobalGoogler's thread on best practices in project structure and was thinking that after all his work in setting up this structure it should be easy for him to replicate this on new projects, duplicating the whole group at once with all the options already set. Maybe it would also be good to be able to save this structure as a template without data fields for future uses. You could then have your personal "library" of templates (for different types of campaigns) from which to choose in setting up a campaign and it would be really fast. Obviously you would have to fill in data fields correctly.
Also it could be easier to share templates that have prooved to be good.
We can already duplicate a single project, we can backup and restore an entire group of projects, maybe it is not so much work to set this up, only Sven can tell...
