Yo Seråh, welcome to AD Don’t worry much about noob-ness, practically every guild out here is happy to adopt newbies who want to learn.
I’m going to link you to a comment I’ve written previously to someone in the same situation as you. It’s aimed at helping you get started on RP and decide on what kind of guild you’d like to try out.
Your guildies will probably be more than happy to take it from there in teaching you the ropes.
Hope this helps and again, welcome to the community, good luck in your search for the right guild. Which you can then narrow down further by following Arethorn’s good advice above.
Edit: I’ve added a link to the guide for new RPers, as well as a link to our Useful Threads stickie that has a wealth of cool race-specific and topic-specific RP guides.
