I actually would like to start a website in which users can register and each registered user will get a subdomain. Each subdomain will be a drupal installation. I can share the files between installations and keep different databases for each of them (or table prefixes). I checked Drupal multisite, but it is mostly for the administrator who is maintaining the website. I need this functionality for the users as it is there in drupal gardens. I also checked Aegir and seems like its also for admin only. Basically I need the kind of functionality that Wordpress multiste plugin has have. Anyone know any drupal module which will allow the creation of multiple sudomain based websites on the fly ?
BTW, I am new to Drupal so my assumptions may not correct. It will be helpful if someone can guide me in right direction.
