Dr. Wyatt Mangum who presented in November provided the following update regarding the addition of a detailed web page on screen floor top-bar hives on his site at http://www.tbhsbywam.com
The link is at the upper right of that page. The screen floor TBH page has about 30 pictures and plenty of text. TBH beekeepers would be interested in it and even frame hive beekeepers with screen floors hives.
