EditWarnings

• Anybody with access to your database can alter Plugin Uploader and allow themselves access to it. It is recommended that you do not allow anybody access to your files unless you trust them completely. If you hold a shred of doubt, don't do it.
• Be careful using Plugin Uploader. It cannot upload all .zip files, and anybody with access to it (only the Super Administrator / Person with User ID of 1 can by default) can upload malicious files to the Database.
