Donna Anthony, also known at Katricia on the Blizzard forums, has
left Blizzard Entertainment, after only a couple of months in the job.
No reason has been given other than she's left to pursue other opportunities, although what they might be are not clear.
On the up side of this, it seems that now that she has left, there has been more Blizzard forum activity by a wider variety of Blizzard employees.
