My apologies, but I should have mentioned that I was making a general comment, not necessarily related to your own experience (your second category rejection appears to have been a mistake, one I'm certain doesn't occur often); that is, the "you" I used in my post was a generic you referring to all applicants, in response to this part of your post:
It is a waste of time and effort for your reviewers and the same waste for the applicant to need to fill out another application and for the reviewer to have to review it again (when maybe the applicant had the proper credentials to begin with but the category was too big for him/her.)
My point was that there are often reasons for everything, which are not always apparent. Metas have been processing applications for over 5 years now, observing what makes a good editor and what doesn't.
I don’t think that you have statistics showing what percentage of people who did not reapply would have been “one time logins”
While that is true, my observation is that an editor who is rejected with a note to apply again to a smaller category, who then reapplies and is accepted, is much more likely to be a good editor than one who mistakenly applies for a larger category and is then given a smaller category. I don't have figures to be certain of that, though. It may be different in different parts of the directory.
One thing I can be certain of, I have not yet met an editor--myself included--who really had any idea what it meant to be an editor before they were accepted. Quite often the characteristics a person thinks are good things for an editor, like being a good writer, are not necessarily a good indication of how they will perform as an ODP editor. All we can do is continue to do what experience has shown is the best method of processing apps.
I am sure that you don't mean to judge me... (snip) I am not trying to sell myself to become an editor at this point, but I believe that I will need to stand up for myself after your post.
Actually, I believe you could be a good editor, and perhaps I was (apparently unsuccessfully) trying to challenge you a bit to get you to re-apply. I read nearly every thread in this forum and many others each day, but I rarely post. I try to post only where I think the post will do some good. I was trying, this time, to explain that filling out an application for a smaller category is not necessarily a waste of time. Perhaps I rushed the post too much. It is hard sometimes to be sure what tone will be read into a post.
In your case, the accidental denial of the second application is regrettable, but as donaldb said, we have no way to reprocess an application. You could look at doing a third app as a waste of time, but on the other hand, ODP does have its bugs. If you can get by this particular bug, you will certainly know that the other ODP bugs won't be as frustrating by comparison.
