From the lotro forums. If you log into the forums, go to User CP and under Settings & Options, click Edit Signature. Under the Edit Signature box is another one for Character Signatures.
Click the char you want to setup a sig, select the avatar pic you want to include in the pic and it will generate the sig for you. To set it as a sig for the SC forums, copy the url from the 2nd box down. You only need the http part, not the img src= crap. Go into your sig on the forums here and click the Img button and then insert the http link in between img and /img.
