Do you really not know the convention of using []s when editing a
quotation?  It's dishonest to change what I wrote without signalling
that you've done so.

Has the name been changed on the college's website yet?

Nope.  None of these are empty.  You tried to sound smart by correcting
my example with "By the way, one empty set would be sufficient" where my
example had many.  Do you want to try again?
