You could even take things a step further and add the following to your "Config Settings" box at the bottom of the administrator's page...
$config['articleboards'] = 'ubb15,ubb16,ubb17,ubb18,ubb19,ubb10,feat1,';
and then include "$Board == stristr(",{$config['articleboards']},", ",$Board,") instead of listing each board in the file - rather than having the edit the file each time you add new boards, just add the boards to your admin config options page
(my usage of "stristr" should be correct - if not, I think that "SUBST($config['articleboards'])" might also do the trick - i might be getting EXCEL and PHP commands mixed???)
