Nothing. It's being used. I did hear a very unsubstantiated rumor that the WTS was looking to sell it but I have taken that one with a massive pinch of salt and dismissed it for the time being.
Could it be that they disbanded the congregation because they are getting rid of the building?
I've never heard of a congregation being disbanded for "lack of love". But... Maybe it was lack of love for the Gobbering Body and its traveling representatives.
We had a congregation in my area that was full of intermarried families whose members had become elders and there was infighting and favoritism going on to the point that people were staying away from the meetings in droves. The CO came in an broke it all up...moved people to other local halls removed elders and rearranged the whole thing. Perhaps it was as case of them being too much like the governing body?
