Note that each
country has a different requirement for this kind of page.
 Maybe this is a place to asllocate for all wikis? 
 Not sure I understand what you
mean. This site is hosted in France. 
 And I was talking about extending to other
countries but probably I
should have started another thread.
   PS: in the
http://www.xwiki.org/xwiki/bin/view/Main/LegalNotice/ I see
 that you're talking of a cookie, which is probably EU-required. However,
 the text doesn't say that we set cookies from the start on; are we not
 doing that? 
 Are we?  
 Yes, we are. I just tried with an almost virgin firefox. It had no
xwiki.org cookies.
  I thought the cookie was only created when you’re
checking the “remember me” option. 
After I visited xwiki.org's home page I have
cookies for:
- 
xwiki.org:
  - _cfduid (cloudflare loves tracking so as to protect against attackers)
  - JSESSIONID
  - _ga, _gat: Google analytics which we are using (not a very good
example for the others!)
  - mf_user and some mf_xxx (maybe cloudflare?)
So in addition to saying that we set cookies for any visit, we should
also that we let third-party service delivery companies also set cookies
(Cloudflare Inc, Google Inc, and XX).
