world4ch

I want to backup world4ch so that when moot finally DELETES FUCKING EVERYTHING we'll still have our memories and we could install shitchan on our own wobsight and it'd like nothing changed! Problem is I need the help of an EXPERT PROGRAMMER.

I know by asking here I have two problems but where do I start?

It really is a terrible pile of code. Comes from Shii being a dimwitted idiot who majored in religious studies instead of a programmer, I think.
