Rob I feel your pain. I have missions pending as well, but I can tell you straight up it's gonna take a long time before those TOW Episodes of yours will be reviewed.
Right now there's about 50 missions to be reviewed before we can touch yours, since we review missions in the order they were submitted - oldest first.
I feel we have a slight shortage on active reviewers, but at the moment we review more than there are submissions, so the situation should be in control after some time.
Reviewing MP missions (like your missions) can be slower than reviewing single missions due to simply the fact that it needs more people working on it.
I do apologize for the long waits but since the pending list is so over crowded there's nothing we can do but to review from the oldest, doing the best we can as magcuba said, and wait.
