I thought I should come back and let you know that my problem has resolved itself.
I had dutifully gone to others' wordpress blogs, posted comments that I knew would be eaten by Askimet and then waited for them to retrieve them and note it so I could have examples. I saved my examples to a word doc and when I thought I had all the info that would help the support folks, I was going to send it in through feedback as is advised here.
It was however, a weekend (this past one) and so I thought I'd do it on Monday. One thing led to another and it was Wednesday before I could make time to do that. When I logged in to my blog on Wednesday (yesterday), I realized that my own comments weren't automatically sent to Askimet in my own blog anymore! At other WordPress blogs, I'm also back to being able to post again without my comments being sent to Askimet.
So, I don't know what happened, but I do know that for more than a week I was definitely being caught as spam by Askimet over and over. Perhaps it takes that long to get back into the good graces with the Askimet after being flagged bad? Whatever it is, I'm pleased. If it's just a matter of being patient until Askimet re-learns that a person is ok, then the solution is to find another blogger you know at WP and post comments that they know are in the bin, as well as post comments in your own. If both of you then, are retrieving your comments, it seems after a time, Askimet will learn you're ok again.
That's a good thing.
Hope this helps someone else.
