The Newgrounds Matrix adVancement Server (MVS) is a community-run Matrix server for the Newgrounds community. Among the features of the MVS is chat rooms for movies & games posted on the Newgrounds portal.
This extension, the Newgrounds MVS eXtension (MVSX), provides an easy way to view these chat rooms: simply visit a page for a Newgrounds portal submission, then left-click the MVSX icon in your browser's URL bar to open the room in the MVS web client--or right-click the icon to use an alternative Matrix client.
NOTE: Participation in the MVS is limited to Newgrounds Supporters only. For non-Supporters, chat rooms for portal submissions are read-only.
