Thanks, Susan, for responding to my question.

I had looked at the permathread link that Joe provided. Perhaps because the permathreads which are listed are-as you put it-"in various states [o]f evolutuon/editing and organized in different ways as their editor chose to organize them", I was still puzzled about how a permathread differed from a "regular" thread.

I "get" it now. At least I think I do.

And I suppose I'll "understand it better by and by".

Best wishes,
