I had discovered ourbeacon.com via wikipedia. Since it is an open, free for all encyclopedia, it is the primary source of information for millions of people. Unfortunately, the info can be biased on sensitive topics as we have seen lately. However, it does make sense to have wiki presence because it helps the seeker stumble upon the right knowledge. Also, you'll notice that if you have a wiki page, google will throw up the link on the first page. Hence, the possibility of getting clicked is quite high. You can try with a google search for yourself.
The 'criticism of hadith' link is on the hadith page. Just type hadith in the search bar and you'll find it under 'Quranist view'. Will setup a couple of pages, as suggested by Jawaid saheb and send the links to you tonight.
