@Sarah To help others understand who may not already: IORP is a FR/RP Server. This means freeroam/roleplay. With knowledge of proper grammar, one could infer that / means and. So lets say Freeroam and Role play.
This means that a player on the server can create Freeroam and Roleplay usernames, for their account. (Ex.)Freeroam username: TS04
(Ex.)Role play username: Taylor_Swift
Either one is fine here because this is a FR/RP community.
By the way, take it easy on our Chief Executive Officer, he works hard :).
I hope this answers your question @Sarah
