This is a wonderful resource - the best on-line zine (oops, I mean e-journal) for world history teachers.
Depending on how the editorial board feels, I might have an article published in the next WHC.
I found this issue http://worldhistoryconnected.press.illinois.edu/6.2/index.html especially valuable.
And the recent articles of James Diskant have been helpful too.
Oh, and, of course, this journal is affiliated with the World History Association which every world history teacher should be a part of: http://www.thewha.org/
Best,
