Hi,

As the subject says.

The link has to be of the form:
[[id:47191abe-bdc5-4af2-80a5-9709943874b7][link]]

I attach an example file.
When you click on a link of call `org-open-at-point', it says
"No match - create this as a new heading? (y or n)".
This can be fixed with (require 'org-id).
The point is just to require it whenever `org-open-at-point' is loaded.

The version is GNU Emacs 24.3.1.
