4chan and w3m

I'm moving from Firefox to w3m. I use the 4chan extension in firefox, and have found it very useful and would like to use something like that in w3m. Does such a thing exist, and if not, how would I go about making it? It mostly is just a set of links, but I wouldn't know where to start.

Question: in w3m, when I hit ``reply'', it directs me to dis.4chan.org/prog/post instead of dis.4chan.org/post. How do I fix this?
