Welcome!!!
You guessed right! When I first came here, I had absolutly no Pokemon from events or shinyss. I've been here only about 3 weeks and I already have every event Pokemon except Jirachi. (I want to catch the Sinnoh event Pokemon myself.) Just remmber, you can't be rude, you can't trade hacks (Pokemon obtained via a cheat device, e.g. an Action Replay), and all ROM Hacks are distriuted as IPS files (if you want to play Zel' ShinyGold hack, you'll need to patch a clean FireRed ROM with the IPS file).
If you want to trade or battle, post in my theads. (Both can be found in my signiture at the bottom of this post.)
Anyways, welcome to PC!
P.S. Unlike Nintedo's NSider forums, we use gliches and Friend Codes. DO NOT TRADE VIA THE GTS!!! The Pokemon WILL be lost to someone else OTHER than the person you're trading with. However, save the FC for a PM (Private Message). (Otherwise, you won't know who will add you to his/her Pal Pad next!) PMs are like e-mail. You are the only one who can view yours.
