Welcome! Glad to have you with us 
Can be either/or. Planned events are absolutely a thing, but there’s also nothing wrong with taking a stroll and seeing if anything going on catches your eye. If their profile says they’re cool with walk-ups, it means you’re free to engage them in IC conversation. Don’t be shy!
This is a personal preference, of course, TRP3, CrossRP (allows for cross-faction RP), and Gryphonheart Items are my favorite. I can’t speak to GHIs current functionality, as I haven’t redownloaded it yet.
It’s pretty easy, yeah. There are elitist guilds, for sure, but I don’t think they’re the norm. If you give more information on what exactly you’d be looking for, we may be able to even give you a few to look into!
I’d also like to mention that I run a discord server specifically for helping people WrA socialize and share RP info, art, and story ideas. As well as just talking about the game in general, or whatever other nonsense we’re up to.
Go ahead and check us out if you’d like. If not, absolutely no problem. People gotta branch out in the way they’re most comfortable. It’s a good place to start making friends here, if you’re interested.
And welcome again!
