I spent two years using and then administering two RT servers.
I arrived with effectively no real PERL knowledge but a high level of Linux sysadmin competency
I hugely enjoyed working with the system. It was productive, flexible, and never gave me unexplained errors.
Even scripting on the perl api was an excellent experience.
Moreover the devs were extremely helpful in their irc channel (circa 2014-2016 at least) and walked me through a manual upgrade caused by the previous admin customizing the database schema in an unsafe way
