These are the instructions I followed from a previous posting about signatures and it worked for me. Good luck this time!
Go to this link:
http://www.mylivesignature.com/mls_wizard1_1.php
and follow the signature wizard instructions.
Once you get what you want, then choose 'want to use this signature'
then choose the 'generate BB code', then 'generate code for my hand written signature'. When the code is created, highlight it and copy it to the signature spot in your profile
