Tweetbrite, the free Twitter mashup that lets you connect your event registration system with your Twitter account now fully integrates with FormSpring. FormSpring is a dead-simple and easy to use form building application that is very robust and can be used for a number of different applications. It works especially well for event registration forms.

I’ve got a guest post at the FormSpring blog coming up soon that talks about the integration. Basically, you can connect to any FormSpring form, select the fields you want to use for first and last name and the Twitter username, and create a mashup just like you can now with Eventbrite. Every time someone registers for your event, Tweetbrite will tweet about it on your behalf!

This new integration adds another way to pull event registrant data into Tweetbrite for auto-tweeting when new people register for your event.
