A map is required to set tags to your event, and have your event included in the Peatix search results. (* not required for online events)
Please register a clear and accurate venue address. You know you've done it right when the map on your event page displays the correct location. Try not to input additional information as such the name of the building or closest metro station etc. in the venue address field, as this may result in the wrong location being registered.
Also, you cannot set search tags for private events (event page with access restricted by password).
