Interface administrator (in the "$ia" group) is a group which allows users to edit the MediaWiki namespace (which contains all system messages) along with sitewide and personal CSS, JavaScript, and JSON. Because editing the interface for the entire wiki or for certain users can lead to potential security issues, you should be careful who you give this to! Only give it to trusted users. Administrators can by default also edit the interface, so this group doesn't need to be granted to administrators for them to be able to edit system messages or sitewide/personal CSS/JS/JSON.
