Folks:
Over the last few days I've been getting people complaining that Wordpress isn't letting them comment because it says their e-mail address is associated with a Wordpress account, and they need to sign in at Wordpress, etc.
To be clear: I don't know why that's happening and it has nothing to do with how I'm running the site; on my end I have the same comment policy I've always had.
I'm having the same issue, and since I'm a lazy broad at times, I'm going to allow Mr. Scalzi to do the talking for me.
On occasion, I have run into this problem when I’m not on my home computer. Since I am insanely anal, I try to remember to copy my comments before hitting the “post comment” button should the comment not post and then disappear. It’s an extra step but it helps keeps my blood pressure level.
