OP, I definitely understand your general sentiment of not feeling welcome. When I first joined E4 I was also new to collecting, so there was a lot of threads/conversations I knew nothing about. As my collection grew, so did my time on the forums/discord and my knowledge of different topics/sets/cards. I feel like now I do have valuable input on some topics. But that doesn’t stop me from lurking about card threads that I know nothing about/have no knowledge on, because that is one way we can learn more.
Also, I try to create threads that any collector can contribute to! I definitely suggest checking out these kind of posts as you do not have to have been in the hobby for xx amount of years to give your opinion on your Favorite Pokémon to Eat, or your Top 5 Favorite Pokemon Cards!
Also recommend checking out these threads as well: Giant Art Thread , Favorite Pokemon
