Question

CMS

Hello. Decided to zababahat Kor. drupal based portal. To think, it's not so difficult - to install the necessary modules, develop a design, etc. In general, such an idea is to set a password for the entire entire project, that is, only registered users can have access to the portal, but registration is closed, only administrators can register. but you understood the idea, you enter - login password, no, so get out of here. Thank you Zorania!
