Heya! We’d love to have you join our community. I’d recommend starting by joining the RP faction discord of your choice. Introduce yourself to the community there, and then keep your eye out for events to participate in, or guilds you’re interested in joining.

Horde: https:// discord.gg/ X3Vj8BD
Alliance: https:// discord.gg/ uHMMRST
As far as addons go, I’d recommend getting TRP3 and filling out your profile. This will let you see and be seen by other RP’ers in the world.
As far as what to do/ not to do, be a positive, respectful member of the community. Show up to planned events if you’re able, participate in WPvP battles. Have fun! That’s the most important thing. Just follow the general “don’t be a dick” rule, and you really can’t go wrong.
