An accurate description of $πN$ scattering has been obtained. A preliminary description of $π$ photoproduction is also discussed.Invited talk. 11th International Conference on Meson-Nucleon Physics and the Structure of the Nucleon, Sept. 10th-14th 2007 (MENU 2007), Juelich, GermanyNuclear Theorytext
