I am using Acquia Desktop for creating multisites. Problem is whenever I am installing a module it gets replicated in everyother site. What i need to know is that if i want to have a module only for specific site do i need to first manually create a modules folder inside the site folder such as practice.localhost\modules (where practice.localhost is the site name) folder as the modules directory is not created by default for any of the subsite folder.? Is my approach correct Moreover I have also heard that if we create modules for specific sites then we are going to find it difficult to export sites to FTP for making the site go online.?
