Not a native English speaker. In my dictionary "plex" has the meaning of "many things". Also I heard of googleplex. And the software manages many git repositories, so I use the name "GitPlex".
There’s a good chance the commenter you replied to meant confusion with Plex the streaming media server, too.
Yep.
Are you by chance the same viper007bond from wp-hackers I knew 10+ years ago?
