I am planning to make a website for different type of community. For example different types of developer.
PHP Java Android etc
Each type will have different registration and profile fields. Now my confusion is either I should create multisite network where each site will contain different developers or just single site can does this job wisely?
Some stuffs I need is to allow user anytime start to use other sites like if x user is registered for Java and now he want to register for PHP he should able to place his content without register again and user id also should be the same so whenever I fetch content by userid it will give me all data from different site from the same user.
Another question if you prefer to create multisite than what is the best choice.. sub-domain or sub-directory
