To read this list I use thunderbird:

It's an email client instead of a newsgroup reader. Just filter the php-general messages into a separate folder and sort it by thread. Super easy to use and a very nice piece of software.
I think you misunderstood me. I'm not setting up a newsgroup client for my personal use (actually look into my original's mail header you see it is sent from Mozilla to news:php.general). I'm trying to setup a newsgroup portal for my working group to use. Some of them are quite unfamiliar with newsgroup and have no time to learn to use a mail agent.
