I see Rich saying he replied to Mike off-list, but I was in the same boat. And I had in fact looked in the archive of this list to see if anyone else may have asked about it in the past. :-)
In case someone may seek it now or in the future, I'll just share that I found my abstract by going back to the site, to the profile page, which offers a link to our submitted abstracts: https://cfp.apachecon.com/profile.html You will be prompted to login, and of course you will need to do it however you had before. Not always easy to remember when sites kindly offer multiple login mechanisms. :-) Thrilled to have been accepted to speak and looking forward tot the conference in the fall. /charlie
