I started doing rubygems in Fedora and EPEL back when OpenShift was written in ruby.
Since I no longer do OpenShift, and since it changed languages, I haven't done much with rubygems.
I am still willing to maintain them in EPEL, but not be the Fedora maintainer.
Now that RHEL7/EPEL7 has gone away, there are several rubygem packages that are no longer in EPEL and I am the only Fedora package maintainer.  I would like to pass these on to someone else, or orphan them.

rubygem-appraisal - Last release - 2023, Last update - Oct 2024
rubygem-coveralls - Last release - 2019
rubygem-mongo - Last release - Sep 2024
rubygem-mongoid - Last release - Nov 2024
rubygem-moped - Last release - 2015
rubygem-require_all - Last release - 2019
rubygem-safe_yaml - Last release - 2019
rubygem-sshkey - Last release - 2023

If anyone wants some, I'll give them admin and owner permissions.
I'll wait until the second week in January, and if there are any that haven't been claimed, I will orphan them then.
