Changes at WT land?
Getting rid of regular preaching.... let's say, stop bothering homeowners in a regular basis...and make a big campaign only by Commemoration time. All duds in good standing should participate, that means less paperwork. Concentrate efforts in all the rank and file, make the thing less rigid and more social. Tell them you're gonna testify by living an exemplary Christian Life.
Maybe by 2075, if they still around.
Don't give them ideas BTW.
