Greetings Arianna, and welcome to the forum! It's great that you decided to join, and I really hope you shall enjoy yourself around here to no end.
I too, have yet to read the Silmarillion, it's a bit daunting to me. But I hope to read it soon- just because I love Middle Earth, and desire to gain a better understanding of it.
The forum can be a bit overwhelming at first- so many places to post! It's good just to pick one section [I personally recommend The Green Dragon] an' become familiar with it. Then you can move on, and expand to various area's of interest.
Great to have you with us!
