Darlene, I have a couple ideas.
Go to the 'user list'
Put in qui and hit enter. If you see a user id you think might be her you can click on it and see the avatar to). see if it is. You can put in quilt and hit enter and you can put in just 32 and hit enter.
Another thing you might do, if you remember a specific post she wrote in you can find that post by clicking on your user name, then click on list for topics you created and topics you updated. Once you spot the post you remember she was in you will be able to see how she spells her user id. It may be a little different than the way you remember it.
Let us know when you find her.
