I always found it weird (and would not applaud) when the "sending of love" was to be done via the visiting elder from the congregation next door. (We had a twin hall shared by 4 congs')
If I wanted to send my love, I'd go next door and tell them. Actually, I went next door if certain elders were giving the public talk and I didn't want to sit thru their drivel I had heard before...and that was when I was an elder.
