1. Very easy to use
If you are like us and love to use Twitter, then you'll really enjoy using T-Messenger. It was made from the start to be intuitive, straight-forward and responsive but at the same time to be as ground-breaking powerful and feature-complete as we could make it.

2. Group Management and Filters
How many contacts do you have? Ten? Twenty? Fifty? More than a hundred maybe? Then you know that it's impossible to see all their tweets. T-Messenger allows you to create groups of users very easily and then filter all the tweets depending on the group you choose. Never miss an update again!

3. Instant Messaging
Aren't you tired of having to type your friends twitter usernames every time that you want to talk or respond to one of their messages? Well, the future is here: Instant Messaging on Twitter. Just double click on a contact, send the message and see their responses on the same conversation window in real time. Just like any other IM client - But using Twitter. How cool is that?

4. Drag, Drop, Done
If you ever used Twitter you know how complicated is the proccess of uploading a picture; Click on a button, browse your folders, grab the picture, click 'Ok', wait for an hour, copy the link and then paste it.
With T-Messenger you just drag any picture from your computer, drop it in T-Messenger's textbox and...that's it. Was that so hard?

5. "Computer Friendly"
T-Messenger is light-speed fast, ultra-responsive and has a very low memory footprint. Use it long enough and your computer will wind up displaying a "Thank you!" notification (You've never seen that one before huh?)

6. Smart on-the-fly text processing
Due to the fact that tweets can only be 140 characters longs due to the SMS text messages every single word that you can shrink will allow you to put more in less space. T-Messenger will automatically shrink URLs (That means 'Websites' for the common folk) as you type, and if you exceed the 140-character limit it will make multiple tweets allowing you to post whatever you want without having to worry about making your message smaller.
