Does this punctuation work?

[glacierfanclub]

Media specialist and newMedia Lab teacher Lindsay Clark looks at social media’s ability to spark change and enable communication on a global level -- all with the click of a button.

[Sadsongs]

Punctuation is fine. Capitalisation (missing space?) of "newMedia Lab" is odd. You could say "at the click of a button"..

[Janko]

Yes. An m-dash (or its equivalent, an n-dash inside two spaces) is the best choice of punctuation there. A comma would be too weak, though acceptable, but a colon would suggest that “all with the click of a button” is the necessary completion of “social media’s ability to spark change...”

Margaret Mitchell only wrote one novel: Gone with the Wind.
