No, I'm not from the ATKV. I discovered your draft after I was unable to find an ATKV link for a different article I was working on.
 It looks like you made a few changes and IMHO, it's already a good article.
 Yes, the history of Afrikaans is well documented on the Afrikaans page. But many readers will not be aware of it. I think it will provide some context to mention how rapidly the language was changing when the ATKV was founded.
