How do I put my character's information in my signature?

Get the link of your character and copy it, then go to the top of the page where you see your user name and click on it. Than click on edit my signature and the paste the link of you character on your signature and save your profile.

If you want it just plain and simple like mine, just make a link, like so :

Ursula

If you mean where it's on the right, check this topic for help : Side Panel
