In addition to checking out the above link, you might want to head down to the Valley of Honor to try and get a feel for walk up RP. It may not necessarily lead to any long term RP contacts/stories, but it’s good practice for improvisation and learning the “rules” .
The following addons are also useful.
Additionally, there’s a lot of activity on various public media platforms. I’d say that Discord/Tumblr/Twitter are a better way of keeping up with RP events than the forums are. Just type “Wyrmrest Accord” or “Wyrmrest Accord RP” and you should find them.
If you’re on Discord, feel free to add me Tamani#2391 and I can point you at a couple of channels as well.
