If you can't find help for your problem on line and you have WWW access, you should see http://www.redhat.com/support/mailing-lists/. Here you can search the archives of the redhat-list. Many questions have already been answered there.
The subscription address for each of our lists is:
redhat-list-request@redhat.com
redhat-digest-request@redhat.com
redhat-announce-list-request@redhat.com
redhat-devel-list-request@redhat.com
rpm-list-request@redhat.com
axp-list-request@redhat.com
sparc-list-request@redhat.com
To subscribe, send mail to the address of the list you want to subscribe to with subscribe in the Subject: line.
To unsubscribe, send mail to the address of the list you want to unsubscribe from with unsubscribe in the Subject: line.
Then to send mail to the list, you just send it to the address above without
the -request in the name. The only exception to this is the
redhat-digest@redhat.com which is only a digest version the
redhat-list@redhat.com. In that
case the address is
redhat-list@redhat.com.
Another good source of help is the comp.os.linux hierarchy on USENET. If you are familiar with news, you should check it out.
