[ale] Question on Current Red Hat Update Policies

[Greg]

I abandoned RH for my home use when they let go of the home user market and
now I am faced with having to use them for a project.  I have downloaded
RHEL 3 and Fedora Core 3 and was wondering if one needs to buy a
subscription to update RHEL or not.  I was also wondering what (if any)
differences there are between RHEL and FC besides the official RH company
support for RHEL.

TIA,

Greg
