It’s not just because of the wp-insert plugin. I don’t use that and had the same issue. It was another plugin messing things up for me. But thanks for the info. Confirmed a suspicion and all fixed now.

This design is wicked! You definitely know how to keep a reader entertained. Between your wit and your videos, I was almost moved to start my own blog (well, almost…HaHa!) Great job. I really enjoyed what you had to say, and more than that, how you presented it. Too cool!
