–30– has been traditionally used by journalists to indicate the end of a story.
Ella Anderson says the end is near. After putting her bimonthly St. John-based Sun Times magazine up for sale last summer, and not finding a suitable buyer, she pushed on through the winter season. But, no mas.
On the Sun Times Facebook page, she said, "I am announcing that the March/April issue … will be the last issue under my guidance. The magazine is still for sale, and may continue under new owners at some point, but for me the journey ends with the next issue; with much deliberation I have decided to move in another direction with my career."
