I've got several sites using my forums through co-branding and I need a way to modify index.php so it appears different for different sites. e.g. just use index2.php instead.

What I'm trying to do is reorder the way the forums are displayed on the front page. I can't just change the orders as this will affect all sites. I need a way to possibly alter the SQL statement to be e.g. SELECT * FROM forums ORDER 2,4,1,6,3 etc.

Anyone got any ideas on how to do this? Or could use PHP to somehow reorder the forums rather than rely on the database?
