Does anyone know if there is a way to detect if a visitor to my site has the webfetti toolbar installed? I can offer money for a solution if something can be put together.
I don't think it's possible unless you are using another plugin that must be downloaded to the clients PC and that option isn't cheap. Other possibility is that the toolbar adds also the info into the useragent string, than an easy javascript/php script can read that information. If so (useragent string) PM me
