Judith of Flanders 

In the article on Judith of Flanders, I cited Asser for giving Æthelbald a reign of two and a half years, and an anonymous editor changed this to four years without explanation. I changed it back pointing out that four years contradicts the source cited, and he has again changed it back without explanation. I see that Janet Nelson in her DNB article on Æthelwulf also dates Æthelbald's reign as 858-860. I have been lucky enough not to get involved in edit wars before, and any advice would be welcome.
