The first time I read the announcement,my brain put the "s" in and I read it as "championship".
Years ago I was told that,when you read something,you read what "should" or what you expect to be there.
That's what makes a proof reader so important.
As a test,I asked a few of my employees read the announcement.
None of them caught the error until I pointed it out.
That's not meant to justify this.
That's why in my office we double proof pretty much everything.
Also, the F7 key should have caught that in spell checker.
Unless, of course, the perp made that mistake a lot and had accidentally registered that misspelling in his dictionary. I've seen that happen!
