I´m working on a city portal´s new edition. The former site used Wordpress, with "weekly theme" , with different plugins. Should I use multisite or single wordpress?Which framework or theme would be the best? here is the list of the features what the site should have: news, classifieds, directory, events, a great video and photo gallery, restaurants with actual daily offers, exclusive offers from selected merchants, real estate, gas prices, etc... The signed in users should be able to post in events, classifieds, directory listings, real estate what would be confirmed by admins before going online. I really look forward to the suggestions!
