Helping them with their latest book project and their futures ones well. Their companion website and blog. So on after that.
Found its really helpful no matter what since 2002. Wish I known about OBOS earlier then that, but can't dwell in the past. Not just their book/s, but website and their blog as well. Will continue to found it useful in the future as well. Have recommended OBOS in numerous responses on a board that I belong to and etc.
