Requested feature overview description.
DeviantART allows you to receive submissions from groups that collect them. In the same way as if an artist that they've subscribed to, has their work appear in their feed like on furaffinity. The equivalent of 'groups' for e621 are 'sets'. A 'set' is a collection of artworks that have a central theme or common feature. This is different from a 'pool' which ties together submissions that were divided up into parts (A continuation of a single piece).
e621 has an advantage over DeviantART and other sites in that it's members collaborate by selecting artworks from different websites, including DeviantART itself, and linking them here in one place. If this site allowed people to subscribe (Watch) a set so that a folder appears on their profile, this website would greatly increase its visitor and user-base.
Why would it be useful?
- A 'set' on e621 would become a subscription to several artists, across several websites.
- Instead of subscribing to an artist, users will be receiving art that is based around a specific theme. This also allows them to filter through the types of posts they receive.
What part(s) of the site page(s) are affected?
The format and locations of buttons / boxes will be up to the website editor to decide. The folders containing the 'set' folders can be located in their profile. This would allow people visiting their profile page to see what sets they've subscribed to, unless the website designer opts to hide them.
Would the admins like to contact the site owner and ask them whether this change is feasible?
