I have Spam Karma 2 installed on my blog; it seems to supercede the "require approval" list in Options > Discussion.
However, I'd like to instruct SK2 that if anyone posts using my e-mail address, it needs to be sent to me for approval prior to posting. This way, I don't have someone impersonating me on my blog. (It's not that I'm especially concerned about it, but it was recommended in a post I read somewhere.)
So, any idea how I might tell Spam Karma "if someone posts a comment from e-mail address email@example.com, then you should ask me to approve it before posting"?
