Speaking of "registrate" (which I did in my previous post) I heard someone use the phrase "administrate a server" the other day.
Now I think that people "administer a server".
Turns out that "administrate" is a valid word so I guess it's a matter of taste.
You would definitely administer justice, or administer medicine, but you could potentially administrate a server.
I wouldn't though. I'd just administer it.
