Yes you got it right .

I was reading some reviews you did, and it's possible they fell short of the length. Moderators have to approve the thread first by checking that you did 3 reviews that met the criteria. I'd possibly PM a moderator in that section of the forum and see what's up.

To be honest, I'd guess the reviews were too short (I believe it's 2 PARAGRAPHS minimum), but I could be wrong.
