Holy ****. Sorry in advance if I miss someone, this is a LOT of sigs.
Ampy: You definitely did not make the art inside the banner. You need to give credit for it.
junpearl63: It's fine if you made the image.
Pamizard: It's fine.
SHINY CATCHER: Well you're banned... so come back when your ban is over.
Lil Crickee: The banner is too big.
Flurried Rains: It's fine.
Mel-Girl: It's fine if you made the art in the banner.
Double-oh-Platypus: It's too tall.
venra77: You need to give credit or properly link back to the sites the images are from.
Infernape Rulez: The banner is too big and you need to give credit if you didn't make it.
frostypookie: The top banner is too big and you need to give credit if you didn't make the bottom one.
Rosemary: It's fine.
Lucariofan-atic: It's fine.
zhanton: It's fine.
Darkrai00: It's too tall.
Kakashi-Sharingan Warrior: That's a default message, if you're sigbanned, you're not allowed to change it so there's no point in checking. As for the rules, every single person is expected to read the rules and know them, they really are not hard to learn, and this thread exists. Warning PM's are a complete waste of time on the part of the staff because we don't have time to baby people and check up on them to see if they changed it. It's your own responsibility. Being a member for so long you'd think you'd know the rules by now, no? Also don't spam up the thread by replying to other people, thanks.
CAH: It's fine how it is, and since it's only size 3, I don't know why a mod would change it. It's most likely that you did it yourself, since if you break the rules, you will get a message in your signature saying so and a usernote recording your offense.
EDIT: Awww, Eefi beat me with that huge load lol. Oh well, I'll leave it up here anyways since it took forever :B
