+Subject: [PATCH] Add root/admin user detection
+
+This patch detects whether or not the server is currently executing as a privileged user and spits out a warning.
+The warning serves as a sort-of PSA for newer server admins who don't understand the risks of running as root.
+We've seen plenty of bad/malicious plugins hit markets, and there's been a few close-calls with exploits in the past.
+Hopefully this helps mitigate some potential damage to servers, even if it is just a warning.
