Similar Websites for Other Antiques?

Hi there!
I am brand new here and I love it! This is just so helpful, I may finally find some answers to all these miscellanious pieces I’ve pick up over the years! Unfortunately I have some questions about pieces that aren’t silver! Does anyone know of any other websites that offer a similar forum but for books, furniture, jewlery or art? I just think this is such a neat idea, and a very useful one at that. Any suggestions would be great!
Thanks so much!
