As some have pointed out in the comments section, we appear to have some issues with our blogs. Other people’s user names and e-mail addresses are showing up on screen of other users. That’s leading to some people posting comments under other handles. I’ve alerted our technical team and hopefully they can get it sorted out. In the meantime, please make sure you look at the user name that shows up before you post your comment. You may need to change it in order to post under your proper handle.
