Support system and Premium Support


I am using Support System plugin and have such question:

I don’t remember the name of second support system plugin, but it is being used on edublogs (/wp-admin/supporter.php?page=premium-support) and it allows users to send mails directly to TEAM’s mail.

If I will make Support System plugin for Supporters only, it will do absolutely same, won’t it? Moreover, it is much more prettier and functional.
