Questions are what I do best.... er, sorta anyway ;P
1. If you take out # banner { etc etc } altogether it should get rid of the residual border.
2. If you don't have tags and what the end of the links rounded instead... copy whats in between the { } from down below.... .module-categories { -moz-border-radius: 0px 0px 10px 10px; -webkit-border-radius: 0px 0px 10px 10px; } and paste is in between the { } of .module-typelist
