You are doing just fine! And here is the story...

The piece was written late last night, and its earlier versions, of course, did not have "a SSA expert" in it. But as agreed upon, 画蛇 would have the last chance to review the piece right before it was to be posted, and she inserted "a SSA expert" at the last minute as a test on whether or not its rightful owner would pick it up. The rest of it, as 画蛇 would say, is history - You passed the test in flying colors! Hats off to you!

Again, as 画蛇 made it clear, yours was a minor oversight in the forgivable category, and the cure lies in being attentive to details. You have just clearly demonstrated that you are paying attention to details.

Thanks for being a good sport.
