Yogadex.org allows teachers to list when and where they teach, and allows students to look up classes in their neighborhoods. This site is unlike other on-line yoga directories, because it lists not only teachers and studios, but specific classes and workshops.

The site collects so much information that building a simple interface is a challenge. Teachers may provide contact information and a description, and for each class a multi-page wizard prompts for all required information, which differs when a class is ongoing vs. a limited time workshop.

With all that data, students may search for classes in several ways. Including by location, class time, style or difficulty. Or by name of teacher or studio.
