I'm wondering if there's a way (plugin or otherwise) to have wordpress post a message to a user's twitter account when they click a button. What I'd like to accomplish is having a site visitor tweet in order to download a PDF. So they'll see a preview of the tweet, hit the tweet button, which will post it to their twitter account (obviously they'll need to login if they're not already) and then they'll be redirected to the results page which will have a link to download the pdf. Here's an old article of an example of someone doing something similar for a music download so you get the idea: http://mashable.com/2009/06/01/twitter-marketing-music/
Any idea how this can be done?
Thanks a lot!
