How about gathering all the information into a single spot on the web
somewhere, with the old patches, ports, etc, along with whatever someone
non-arla aware would need to know (cheat sheets?) to get into the hard
work as quickly as possible? I know next to nothing about arla, but if
the cheat sheets were there so I didn't have to spend a ton of time on
learning arla completely before looking at it, it would make tinkering a
lot easier.
Start a new thread on HFS+ if you need to. :)
