We are using the Events Calendar on a site we manage, Clearwater Casino, and are trying to get Google Rich Snippets working properly.
After finding an old thread, it looks like you implemented Rich Snippet functionality in V2 of the plugin (we are running the most up-to-date version) but Google is still not pulling all of the information we need.
As an example, http://www.clearwatercasino.com/event/seafood-buffet-5/2013-03-01/ is one of our event pages and if it is ran through the Rich Snippet Tool, we get the following results: http://www.google.com/webmasters/tools/richsnippets?url=http%3A%2F%2Fwww.clearwatercasino.com%2Fevent%2Fseafood-buffet-5%2F2013-03-01%2F&html=
It seems quite a few fields are missing, notably the "entry-title" and "author". Do I need to investigate adding these things into the theme template, or am I missing something on where these should be entered inside the Entry posts?
