I am sure you meant to say, "Capitalize after the colon if there IS a succession of sentences," not "ARE."

I am a non-native English speaker. But with all due respect to Gregg, my loyalty remains with the period. We can't have two chiefs; we can't have two presidents. The renegade, envious colon can make trouble and try to convince others, but this reader will capitalize following only one punctuation mark: the period.
