Another option (one that is not getting used as much as I would have liked) is on the Revelations.ParadigmCampaigns.com site. If you go to the "Events" tab, you can search for events within X miles/kilometers from a given postal code. The page works fine. However this only searches for public events that were created in the system. That is, if I decide to host a WH:R game day at my local game store, I should log in to the campaign site (Revelations.ParadigmCampaigns.com) and create a new event. When I create that event, I should make sure the the "Public" check box is checked. If I do that, then anytime someone searches for events within the area, it will show up. (Private events/home games won't show up on this search page.)
The goal is for every event to download the latest adventure(s) and report your results. This helps PCI determine what is being played and roughly where it's being played. Information that can help them to make informed decisions about adventures, special events, campaigns, etc. The more we can get people to use that system, the better off we will be.
