This is a plugin for WordpressMU (it may well work in standard WP too) which will replace any links posted with affiliated versions if they are defined. This plugin can be installed in either the standard plugins or the mu-plugins folder depending on your requirements. Once active, it adds an additional sub-menu option under Site Admin for the site admin user which can be used to set up affiliate links. There are four values to enter - the start of the URL to replace, your affiliate ID for that organisation, the merchant or programme ID of that organsation and the affiliate provider (type). At present, basic Tradedoubler, Affiliate Future and Affiliate Window links are available and more will be added during the testing phases. This is a beta release and therefore should be used with caution.
