Well, my experience has been that there are those who specialize in regions (Devon, London, Scotland), and others with expertise in topics - i.e., immigration, handwriting, or in this case, alias names. In each instance they tend to follow the chat room of their interest - not every chat room. It's been hugely helpful to me over the years to cast a wide net, but only when necessary. And if the information hasn't been provided, what's to lose?
