How do I get my signature back
 

When the website changed, my signature dissappeared. How do I get it back? Thanks

the new format does not support many of the offsite signatures that were previously used.
you can go to Edit Profile and type in a new signature

I have tried and cannot change or even delete the url for "my live signature". Any other suggestions, because the url keeps showing in my posts (as seen below) unless I uncheck the box to include it every time, which is hard to remember.
