remove historical EPEL information?

[Patrice Dumas <pertusus free fr>]

Hello,

As part of th ewiki cleanup, some 'historical' pages will disappear,
like 
https://fedoraproject.org/wiki/EPEL/SIG
or
https://fedoraproject.org/wiki/Extras/Schedule/EnterpriseExtras

Is keeping this information in an historical section worth it? It would
mean adding a page that references all the pages that are going to be
removed such that interested people can save the information on the page
before old pages are removed.
