There aren't multiple threads.
There is one thread, and then a thread form 5 years ago which died and which nobody sees.
I am not saying don't reply to something a month ago...but over a year seems strange...and 2 years, well, ridiculous...
Cycle of nature...everything gets repeated in different guises...old things die and then something very similar takes their place because everyone forgot the past as the generation pass. That's life.
