I will build a Wiki that is to be used by teachers and it will naturally require that they register as normal users. Then I would like them to register a bit of additional data, regarding them self and their schools - like location (perhaps googlemap location), FB page, classes etc.
What extensions can I use to set up and register such a teacher/school information in a structured way. The set ups should be simple, like if you register as a teacher you can enter default information, and then either you must register your school or select one of those that are already know.
