This site looks very old fashioned. Requesting the admin to add some features

EVERY good textboard like goatfinger and 4ct have quote back links, so why doesn't this?

Just because you're trying to make it look like shiichan, doesn't mean you should remove features until it does.

Backlinks are really only neccessary when you have massive threads where people regularly reply to posts that are 10-20 posts back. That makes sense for a site like 4chan where threads frequently get hundreds of posts in a matter of hours, but /prog/ is a lot slower so it's not really needed.
