RHEL entitlements for EPEL maintainers

Some EPEL maintainers do not have access to RHEL to test and develop their packages. This pilot program allows active EPEL maintainers to request a RHEL entitlement to test or develop their EPEL packages. Note that this is a pilot program and could go away at any time.

In order to request your entitlement, mail kfenzi@redhat.com with your Fedora Account system name, what EPEL package(s) you currently maintain, and your RHN login. Note that you must be an active maintainer and have commited/built/pushed/updated some EPEL packages recently.
