Click "Data Link" at the very top of the page. Directly underneath the signature you will see some text, copy that text. Now go to User-CP, can be found at
http://www.planetside-universe.com/usercp.php
On the left side of the page you will see options to customize your profile. Click on "edit signature". Now paste your text into that text formatting box. Scroll down and click "save signature".
Now go post somewhere (there is a test sig thread that I started at
http://www.planetside-universe.com/s...299#post951299). If you still dont see your sig then reply in this thread and Im sure we can figure it out. Also, I hope I am not coming off as condescending, I am trying to help.
