I read somewhere that Vantage can post events but I could not see it in the demo how to do?
The events features in Vantage have not been added yet. We just released Vantage 1.1 and we're starting work on Vantage 1.2. Version 1.2 will include events.
Also is there plans for the listings to show there own deals?
We haven't discussed when and how we would add this but it is a strong consideration.
