I've created regional portal (let's name it region.com). There are several plugins, categories (e.g. news, events). Structure is simple (homepage with all posts and single category sites). Now I want to create cities sites e.g. city1.region.com, city2.region.com etc. I want to have same plugins (with same options), categories and themes on each subdomain. On my main domain I want to collect posts from all subdomains, but I want use different widget options (e.g. slider, context menu) on different city sites. Is a multisite good solution for me or should I use something else?
Thanks in advance
