Hi - this is something that has been asked for many times, and a few folks are working on a browseable list (i.e. , click on Antivirus then click on Kaspersky, etc.)There'll be a spot for feedback, and if the community ever agrees on a process for "certifying" contribs, there's a spot for that, too. Hopefully there'll be something to use in a few weeks.
But it's harder than it looks - some contribs are hosted here, some elsewhere. Links are continually changing. Some were linked from e-smith.org, some never were. Some are how tos only, some have rpms, some are only rpms. Some are fresh, some haven't been updated in a long time. etc. All of the work to get them into the list, or update them, is manual. It seems unlikely that we'll ever get "all contribs" into it. Hopefully the core ones that many people use. We're going to need a lot of help from the community, to tell us about broken links, updates, etc.
So, the upshot is that the weblinks are going to have to be the spot where "all contribs" are available. If something is not there, contact the author and ask if they want to put it in! It's by far the easiest way to let people know about it.
