Welcome to FR.
I think they are now hanging out at the The Hobbit Hole III - Journey to the Cross-roads! thread.
It's located in the General Interest forum.

It's a more general chat site here at FR for LOTR fans, but a lot of pretty serious discussion about the books and movies occurs as well.
There is also a "Ring Ping" list for Tolkien and LOTR articles that is kept by Ecurbh, and you can get on the list by freepmailing him or HairOfTheDog. There are some really excellent (and even scholarly) articles posted on FR regularly.
If you read down through the posts, you'll see a set of direct links to all the articles that have been posted here recently (quite a few, and a number of them are very good). You'll also see the "Ring Ping" that I mentioned before, so you'll get a notice whenever an article is posted.
