About the rules:

Sorry, there is a lot to solve in the tracker, that's why we open registers for few users, the rules will be updated soon with all your questions.
for now only allowed, Japanese anime, and movies or series from the rest of Asia, no porn or hentai allowed, only Pink, the cover is mandatory, and the template for the contribution.

Regarding Screenshot, I think that at least 3 images, maximum 6 would be ideal, there are many contributions for DVD, R2J, R1, R2 Spain, R3 Asia, R2 Europe, R4 Mexico, etc., the same for BDs I think with a few images Users will see the quality and decide whether to download it or not.

---------------------

About documentaries, one documentary by country, that is included in the categories, could be allowed, but first post the documentary in the forum --> offer, so users choose whether or not to upload it, it could be golden forever.

Note: The scans have to be uploaded on the forum.

Note: Changes are still being made, not everything is defined yet.

- EAC/XLD logs are optional at the moment.

- Scans are allowed within the torrent, but if we see that users only do it to inflate the torrent size, then we will not allow scans.

- The staff is deciding whether to use a template or not for name formatting.

- Soundtrack and its scans are not allowed on BD or DVD
