Hello and a heartly welcome to Aaront596 and emry!
To join the project is very simple: read in the threads here in the forum and start commenting on the changes we proposed.
In time when you have shown a real interest you will get a password for the members only forum, which will give you access to some helpful compilations. This access is not a must have for the discussions it is only a helpful addition. In former times a simple message likes your would have been sufficient to get the password but we ended up with a long list of members which never became active. Therfore we only give it now after a time of active participation in the discussions.
See posting 100 in this thread for an oferview of were we are. When we considre a chapter done, that does not mean that you might not start a new discussion on it, but it might be easier to start with a still open topic. Therefore I would recomment to start with reading the following threads:
Narn I Chîn Húrin 1: Túrins Fostering
The Narn i Chîn Húrin: Beleg & Falivirn
Narn i Chîn Húrin 3: The End of the Narn
Respectfully
