I am running YACreaderlibraryserver from SirDocker on my Synology DS918+ in "Container Manager", pleviously called "Docker" and must say that this build is almost perfect for me.
Most of all I like the README from SirDocker which is quite clear.

Although the above, I have some questions:

1. When executing the command:
YACReaderLibraryServer update-library /Strips
I get 15 remarks that RAR5 is not supported, which I am aware of.
Does someone know where I can find what files give the error so I can re-rar them with RAR4?

2. Can I run more than 1 servers since I want some comics not shated to the kids?
Or is there another way to seperate some comics from the kids?

3. How can I get in to contact with SirDocker since I would like to share thoughts about his build.
- How can I resolve the ROOT access issue?
- Can I save the CONFIG files to another location?
- Can different users have different "continue reading" lists in YACreader on the iPad?
- Refresh of library doesn't work for me

Hope to hear some replies since there is not much to find about YAC server on the Internet....

rar5 is supported, but (assuming you are using docker) there are still some unresolved problems github.com/YACReader/yacreader/issues/417

And yes, you can run two servers with two different libraries, they'll need to run in different ports.

I don't know anything about SirDocker, do you have any links I can check?

registry.hub.docker.com/r/sirdocker/yacreaderlibraryserver/

Nice and small image and clear instructions.

I don't see any contact information :/

It would be nice to have all the people working in different docker images working together...

I don't understand what is meant there but sir docker mentioned:
"feel free to contact me by email (you can get an email from the image LABEL email)."
Maybe that is of some help for you.

Another question:
Does anyone know how I can provide more separate "continue reading" lists with the YACServer?
Now every member of the family can see each other's last read comics.

Are these stored in the file library.ydb in the.yacreaderlibrary folder?
If so, would it be possible to have that file created, based on a variable that can be used in the server and reader?

The libraries are single user… So there is no way for having separate reading progress per user. It would be nice to have it, but I am not sure when I will have time to deal with such huge refactoring.
