Well, I've thought to copy all the old threads from this forum to the new forum and start a spunkier discussion about extinct and endangered plants. I think also that it is a better solution than to made duplicate entrees in both forums. And as Noisi has stated it makes both forums clearer.
Well moving would be easy but it is technically not possible so i can only made duplicate entrees in the Vanishing Plants forum provided that i could receive the permission by Sebbe, Another Specialist, Bowhead Whale, Noisi, and all the others who have already replied in the Extinct, Endangered, Prehistoric, Rediscovered, New Discovered Plant threads in this forum for the use of their replies in the new forum.
When you say close, do you mind moving them to the Vanishing Forum?
So the technical facts narrow the possibilities to your original proposal of duplicate all threads and posts (I'm sure everybody will agree), and closing the discussion on plants in this forum. Well, I, for one, support your idea.
