To change your profile picture click on "settings" at the top of the forum. On the left side you will see a section called "My Setting". That's where you want to go to update your profile pictures, avatar, signature, etc.
As for a werewolf RP? The best category would be "other" at the moment. I do want to caution you on a werewolf Rp. RpNation runs a RP based werewolf game that is gearing to release it's 3rd installment. This werewolf Rp usually involves 90% of the active forum & may pull some of the crowd from yours. I would focus on your first RP & create a second one if your first ever becomes inactive.
If you have ANY RP related questions, send a PM over to any of our RP mods as they are the experts!
