[Mediawiki-l] Need to add a disclaimer under "external links" section title

[Chad Johnswith]

Racking my brains and searching on this, what file will allow me to do this?

Our company requires we warn people that we do not control the exteranl
links and that content maybe questionable etc.  They want the warning right
under the line under the title "External links" and above the links
themselves.

Thank you!
