Each time you add a new event you have a choice. You can either add a new venue or select a venue you have used in the past. However, as the functionality is new, only events currently listed have the venue information copied over.
Additional work is being done relating to the venue associated with an event, so if you would like to request some changes or additional functionality, use the contact us form on the site to let us know.
Members of the site can create their own blog, posting about things that relate to thier business or craft.
