I think I know what you're talking about. just click on the 6.72 beside the linux link. if it's like most other online hosts that have multiple versions, it will only cache the 6.72 host page and payloads.

I don't know about the user guide. I just use the browser. you just have to find one that works well. I think someone made a psphive modded self host with at least goldhen, not sure about the other. it's supposed to work very well.

if you don't want the trouble of adding the payloads, just replace ones already there. it will work. it would be much easier, but it would require self hosting if you're okay with that.
