I have a dedicated server running Plesk 6. I have about 60 domains that I want to setup on the server...all with the same amount of space and everything. Is there some way I can do them all at once rather than having to do it over and over again 60 times?

you cant setup multiple domains at once, however you can setup domain templates, there you can set limits, such as emails, space etc. etc. then when you create a domain just set the template you created. you can make client templates and domain templates.

Check the creation utilities (ftp.plesk.com), it might be quicker to do it from the command line than trough the interface.

In Plesk 6 you can check the domain names and then use the button "Global Changes".
