The index to the old forum is shown in the new forum for your convenience. The old forum is still the old forum.
The new forum has 10,030 posts as this is written (and increases every minute) while the old forum has 354,804 posts (and is locked)
I think, you didn't understand, what I want.
Is there any Forum-Post from the old Forum (2005-2010), that I can not reach under the new URL "http://arduino.cc/forum/
If yes, tell me the post.
If no, what is the reason not to force the search engines to only index the new URL "http://arduino.cc/forum/
