   Hi Joe,

   I hope you can help me,

   I am trying to track all twitter traffic by adding a property ?aff=tw to all URLs before the shortening happens. How can I add it?

   Thank you very much for your support.

   Hmmm. There's a way to do it using a custom filter.

   There's a filter applied to links prior to sending them for shortening called 'wpt_shorten_link', which excepts as arguments the link itself and the post ID for the post being handled. If you add a function to that filter that adds that attribute to the URL, that would work.

   You'll want to look at the codex for add_filter:

   http://codex.wordpress.org/Function_Reference/add_filter

   This is fairly advanced, but WP to twitter doesn't have a system for adding custom attributes to the URL. Alternately, you can add a URL in a custom field that you use instead of the default permalink; but that would be more labor intensive in the long run.
