I am creating a board that will present national events as well as local events. Once users register, I would like them be directed to their local category based on their location and also have access to the national category. For example, if a user is in New York City, once they register their home page will have a category of national events at the top and a category of New York City events below it. Is there a function/extension that does this, possibly using google api? Please let me know if I can provide you with additional description.
