Just a heads up - Pokémon Showdown was hacked a few hours ago. From their forums directly: "PS has been compromised. Until this message is removed, you SHOULD NOT try to log in to PS and you SHOULD change any passwords that are the same as, or similar to, your PS password. More information will come when the situation has settled." I strongly recommend heeding that advice! (Thanks @[member="Achromatic"] for letting me know.)
Oh... Yay. Though, really the odds of you being compromised are at least 1 in 500,000. Not saying you shouldn't heed that advice, but don't panic about it. I've seen more than a few people lose accounts because they panicked, changed passwords and forgot said password. It's worse when that password was used across several different accounts for different things. A lot more work to recover the passwords.
