I RP on MG on an alt!
TRP3 is a bit of a doozy to get used to. I used MRP when I first got started. It’s a great intro to RP add-ons.
WoW Instant Messenger is also great, not just for RP, but for managing your whispers!
It’s a lot of fun, and Moon Guard has some cool raiding guilds too if you wanna get some content done too!
And despite what they say about Goldshire (It’s true), it’s also a good place to find PvP goons for Arenas. They’re surprisingly good at it.
