Implementing an imageboard

I'm close to finishing my imageboard implementation. It has all the features of 4chan except for /f/ and /rs/ and so I have a few questions:

1. How is /rs/ implemented? Does the site scan the links posted in each board? Unlike /f/, /rs/ doesn't have an upload form.
2. How do the implement capcodes (what is their input syntax) and how are site moderation and administration performed? Where do they login? Do they have username and passwords? What's the admin/mod panels look like? Can moderations be done in-site and not only through a dedicated admin panel?

The board has everything except images stored in memory so it should be fast. If there's enough interest I might be able to open source it once it's done.

Will it ever get used?
Most likely yes, I'm thinking of setting up an imageboard specific to my country..

Isn't the best admin/mod workflow is to have the same interface as regular users but sparkle bits of admin controls here and there? Currently I have a separate admin panel that's going to be in a separate subdomain altogether, but I'm planning on adding in-site admin/mod controls.

Just write some scripts you can run serverside and do your adminstration over SSH.
Although this would probably be the most secure option, administration and moderation would be tedious as I would have to, e.g, go back and forth just to check if a reported image is really against the rules etc.
