I see you have gotten plenty of good advice already, so what I say you might already know!
So, for starters I want to link you a very useful page that a majority of us use to keep up about current events in the various communities.
There are Discords too, but for starters these two links will do 
Argent Dawn EU: https://discord.gg/Ebg6kZz3
An advice I got when I first started was, play a young character, or someone looking for X shop, or place, or pretend to want to buy something.
I have had the pleasure of interacting with lots of new role-players such as yourself during weekly markets and the soup kitchen in my community and, that is always welcome.
Often, they give me a whisper that they are new, and from there we work things out together so they get a better understanding of the world they step into.
It’s also worth mentioning for you, and perhaps others too,
that if you use the TRP 3 - roleplaying addon you have these neat features to show your roleplay experience.
