Plesk Question
 

Does Plesk allow addon domains like cpanel? I've been trying to find out and haven't found an answer yet. If it does, do the addon domains count against your total domain license or does plesk look at the addon domains as 1 since they're for 1 account.

It depends on your host. There's pachages, I know of two, which are 30 domain license and Unlimited.

I'm doing a dedicated server with cari.net . I want to offer addon domains for proxy networks and I don't want to have to give out a different account for each domain.
