Open the Server Manager on your neatComponents installation.
If no Users have been created, right-click on 'Child Sites', and select Import Site from the context-menu. You will be able to select the default User you created during installation. A matching User will appear in the tree automatically. Browse to the location you saved the ncx export-file, and import.
You can also create a new User who will 'own' the imported Blog System. Select the 'Users' menu entry at the top of the page and follow the wizard to create your new user. A matching entry will appear in the tree. Right-click, and select Import Site from the context-menu.
3 - Set the site access
Set the site access to the domain you want your new application to respond to - for example: http://twitter.example.com then leave the Server Manager.
You can now access the application directly from a regular browser session for configuration and use.
