tutorial or something like that, on how to make packs
mmm. it's very easy, and took about hour to complete, most of which is scripts work. there is no need to help (better to edit tags or donate).

That's also A LOT of bandwidth we can't afford.
and that's the point of making these packs. hanyuu mirror is in the same datacenter, so (afaik) it isn't counted against konachan's quota. traffic of mirror is paid by me and torrents are paid by peers

if it were possible for any random user to make their own packs, they could easily just download the whole konachan
technically, it's possible right now. anybody can get all posts through public interface, but judging from logs, there aren't many people consuming packs.
