Export projects, so that I can share the project setting within team

We are two persons working on the same project. Each of us has to add the same project information for his account separately, that means the same information, twice. Let's consider adding another person to the team, that person also has to do the same, and it goes on…
This is becoming complicated for us since we have to add new projects, at least twice a week. This could be resolved if we were able to export that information separately, and import it on each account, so only one person could create the tasks, and the others could just import and add them to their current base.
