I tried changing, Village "mistook sex toy....",(the thread I wanted to adjust) but also tried to change thread titles on 2 Million Tons of Rice..... and Bank Indonesia Refines...... to see if it was just one thread affected. Thread Title Edit didn't work on any.
Maybe forum demographics but how about the car and vehicle become about cars and not just selling old ones? That could be a sub section.
Also bikes could be separate.?
