Hi,
I'd like to reiterate a suggestion I've made in a different place. In my not so humble opinion, mailing lists are by far the best communication tool for Linux distributions. I've been a subscriber to the CentOS mailing list for the last 15 years or so (since around 4.x). Setting it up in your mail client is trivial, and whenever you have to search for that precise bit of information, you just fire up Google and point it to site:lists.centos.org and there you have it.
Cheers,
Niki
