Hey there and welcome to the forums, Cardinal! I really haven't tried hunting a Shiny pokemon before but it seems lots of fun, I really just don't have any interest at it at all, but I'm very sure that some of the members here has the same interest as you do most especially the people around the Trade Corner who really loves to trade shiny Pokemons, if you want you can also make a Shiny Fan Club on Pokemon Groups if you're interested and there are tons of other groups there as well such as those that Twiggy mentioned! :P
Besides the two boards that I introduced you to, I'm pretty sure that you will also love the Pokemon gaming boards wherein you can discuss everything about the games. You can also share your daily journal if you've just started playing once again or if you've restarted your game! It's a lot of fun so I doubt it if you wouldn't find it really exciting 'cause everyone does! Haha, but yeah PC Isn't just about Pokemon as you can see, it's also about building friendship with the people around, so PC offers you the off-topic boards wherein you could discuss anything that isn't related to Pokemon, the reason why many people enjoy going to this place! :D
We're definitely looking forward to see what you're gonna contribute in here, but before anything else, you must first read the rules if you still haven't so, so that you wouldn't get into any trouble, and after doing so, you must always keep in mind to follow them as always. With that, I can guarantee you that you will just be fine here! ♥
If you need some help, feel free to contact Megan and I, your NU/W Moderators! You can also contact the other staff members around in case we're both not around. If you want to talk, you can leave a message on my profile as well!
Have a great time and I shall see you around thennn! :3
