For a Client i had evaluate JobBoard before. It is also a goog component, but the publishing date couldnt change in the backend nor in the frontend. I switched to Neorecruit. It was very easy to setup. Now he can change the publishing date. Also very fine are the url's. The are taken from the categories and title.
What i'm missing are the social plugins. I asked the support and they said this feature is planned, but if needed urgently, they can help me out.
