Quote:

The phrase "get across" does not form part of standard English; or of any variant I am aware of. Where do you get it from any why do you seek to promulgate it to your listeners; many of whom are seeking to inprove their comprehension of our language?



so the original use was "get across"?
as in "Our message will be very hard to get across."

that's really a pretty common usage. and, I suppose, once you've gotten your message across, it then becomes a matter of keeping it across.
