I just haven't been able to get this after reading many examples. I'm trying to add a facebook login button to the top links. I can get thew block to show up all over the place but not in the top links.
This last atempt makes all the links disappear:
<reference name="top.links"> <action method="setTemplate"> <block type="fblogin/fblogin" name="fblogin" template="fblogin/fblogin.phtml"> <action method="setAttribute"><key>position</key><value>1</value></action> </block> </action>
