Back in October, I alerted you guys to the Codex Sinaiticus online, and it is now available at http://codexsinaiticus.org. I had previously directed you to what is the homepage, http://codex-sinaiticus.net, but the "See the Manuscript" tab directs you to the .org site.
It is a great resource. Go have a look and play around a little, you won't be disappointed.
