In an effort to make things easier to find, i've started this up.
It's a repository of information and SOME cabs for PPC's and other devices (just 2 for now).
Check it out and sign up/contribute. There are some guidelines but the main thing is, if there's a program/tweek that is updated regularly, link directly to authors page with dl from their site - this way the most current version is accessible.
For programs that are no longer maintained upload it to the site.
The repository is located here:
