Hi

If i have 2 diferent business and i am abou to create 2 or 3 more, what is recomended for me?

Create a multisite with all of my sites for being controlled from one place? or create 5 different instalations of wordpress?

I supose that if i want to use the users of diferent sites among them would be the best solution, multisite, wouldn’t be?

Thanks
