little bugfix: if you allow signatures with picutures in it and the user make it as link you see my little link grphics in front of it. This look odd. You can fix it if you add this code in extra propertis in the style editor:
.signature a:hover {
background: none;
padding-left: 0px;
}
.signature a:visited {
background: none;
padding-left: 0px;
}
.signature a:active {
background: none;
padding-left: 0px;
}
