Sorry, no, comments and reviews can not be left for a listing and there are now other plugins available that will allow it.
The release date for Contact is unknown at this point. I think I’m going to dedicated the week between Christmas and New Years to finish off both Contact and Authored.
All templates except Market work well within responsive themes. They all have been tested in Twenty Twelve at various screen sizes.
They isn’t a specific search for city/post code. However, there are setting on the Connections : Settings admin page under the Advanced tab that allow you to turn on make the city and post code in addresses links within the listing. When a users clicks on one of those links, the results will be filtered by the link clicked. I hope that makes sense.
I do not have any specific example to show you of how others have used s2member because I haven’t kept a log of those that I have helped by answering support questions.
I hope this answers your questions thoroughly.
