I've looked over the list and to the best of my knowledge, none of the stories listed were ever included for Kerth consideration at the time of their posting on the MBs.
This is true for a couple of reasons. First, I always used the uploaded to the Archives 'rule' as my guide for eligibility. And, some of these were only added to the archive last year as a means to have them somewhere else if my own computer hard drive should ever crash again.
So for whatever it's worth (which isn't much). These stories can be taken as eligible for anyone who wants to see them that way.
Tank (who noticed a couple of 'Tank endings' in the mix and thinks they are hardly serious candidates for consideration)
