We may have exactly what's right for your. Our WordPress plugin allows you to upload any file you want to make it available to any Twitter user. To access your file, people are asked to follow your Twitter account and to send a promotional tweet. That's what we call a win-win Twitter exchange file process.
When installing the plugin, you set up the promotional tweet in question so there's no surprise afterwards!
Pairing Twitter and WordPress with an eye on exchanging content seemed very useful to us and we're convinced you can benefit a great deal from such a tool.
Twitter exchange file might be the answer to a lot of your needs. And since it is entirely free!, you'll have no excuse if you fail to use this Twitter exchange file solution.
