That's interesting:
"The workshops are open to all Afrodescendants including but not limited
to individuals who self-identify as African, African-American,
Afro-Latino, Biracial, Black, Black-American, Caribbean, Garifuna,
Haitian or West Indian."
I've never seen editithons that exclude people before. I've been to a couple of black history events, and all were welcomed, although of course there was a very high proportion of African descent. Likewise, the women's editing events I have attended have been very welcoming to men, although as you would expect, there is a very high attendance level for women.
