The same way you put down one signature. Go to 'Settings' in the top right corner > Then scroll down until finding 'Edit Signature' on the left hand side > Then click 'Add Image' on the second row > then put the link to the picture that the designer provided for you in the box. Then that's it. It should be there. Hope this helps
Haha thank you sir...I was recruited in 2012 to help rebuild DarkAges...it was a great group of guys over there and had alot of fun...wanted to do a sig for that and Bizarre wanted one as well
