Collecting Art Forum (oil paintings, sketches, prints, etc) that’s similar to Steve Hoffman forum?

(I hope this is posted in the correct category?Apologies if not.)

For the last year I’ve been purchasing signed oil paintings, sketches, #’d reprints etc at local thrift stores. It’s been a lot of fun, simply buying what appeal to me. I have identified some of the artists, others I have not.

Is there an equivalent type forum out there for novice collectors of art similar to what we do here?
