I learned that the California Law Review requested that ExpressO add a feature to solicit demographic information, such as race, gender, and sexual orientation. ExpressO refused to add this feature. This angered the California Law Review. The California Law Review left ExpressO for Scholastica, in part, because of their refusal to add this feature. Scholastica ultimately accommodated this request.
