naqshbandios_limra, you REALLY need to sit down and think about what you're doing. You cannot just update someone's work without permission. Doesn't matter if you give them credit for it, it was their original work and you cannot just go around updating it when you like, especially when it specifically says you can't like in the link labrocca gave. If people update a plugin and give credit, it's because the original author has given them permission to do it.
Please think about this in future. You're making a lot of people angry quite quickly.
