I cannot find where to change my signature. I did it on Yahoo, but the changes are not coming through on the LSNW list. Where can I find it?

When you are online at the groupee site, there is a stip of options at the top of the messages. Go, New, Find, etc. Click on Go then My Space, then Profile. Then your member profile will come up. On that profile is a "view/edit complete profile" link. Click that then you can change your name, signature etc.
