wriga,
Welcome to the forum.
The forum rules are that you have to make 10 (?) posts before you can make a link. The url below is, I think, the one you intended to make:

The great advantage of NeuroTalk is that a thread has a much longer history than on other forums. It is not uncommon for a thread to be added to five years after it was started.
