Forum:How to remove the arrow next to the external links?

How to remove the arrow next to external links? I really don't want it. Is there anyway disable viewing those arrows in a whole wiki? If so, then where? What do I have to insert? &mdash; [/wiki/User:Sam_Wang S a m ] [/wiki/Message_Wall:Sam_Wang W a n g ] 11:15, February 17, 2012 (UTC)
 * You need to put the EL in a span with class plainlinks. example . To change it across the whole wiki, you can probably apply the CSS for plainlinks  to a.external --  Random  Time  11:22, February 17, 2012 (UTC)
 * What do you mean? Are you talking about:

 .external a { background: none repeat scroll 0 0 transparent !important; padding: 0 !important; }  &mdash; [/wiki/User:Sam_Wang S a m ] [/wiki/Message_Wall:Sam_Wang W a n g ] 05:00, February 25, 2012 (UTC)
