We hate auto-tweeting and believe that you should always give explicit permission when you tweet something out. This is something very important to us that we vow to stick to. 
You'll notice when you sign up with Twitter, we do ask for write permissions. This is so we can build out options in RebelMouse that will improve your experience. For example, being able to follow someone in one click, and tweeting directly from RebelMouse where we build the dialog options directly into the app (similar to how social media management apps do it, to make your life easier). One thing we will definitely stick to is absolutely never tweeting without you explicitly choosing to do so.

If you have *any* concerns or further questions, please don't hesitate to email us at early@rebelmouse.com and we'd be happy to chat more.
