Awesome Mod is a mod created by J. M. Pescado which can be found on the "Awesome Mod!" Board at "More Awesome Than You!" here: http://www.moreawesomethanyou.com/smf/i ... ,31.0.html
To make a long story short, Awesome Mod is a core mod (meaning, it is a HUGE mod, and you can only have one core mod) that tweaks the game and adds new features. The mod is for power users, and is not simple to use. However, that doesn't mean its hard. The mod was released 2 days after the game was, and has been updated frequently ever since. The mod currently works up to the 1.18 patch, and if you want to go further in depth, there is a test version that is updated almost daily.
The mod is huge, and you should read the features before you decide whether or not it's something for you. A lot of it is nit-picky changes. However, it is definitely a game changer, especially for power users. It's hard to stop using it once you've started!

I should let you be aware that the people at MATY (more awesome than you) are VERY sarcastic, rude, and barbaric. DO NOT, I REPEAT, DO NOT post a thread asking a question. THEY WILL EAT YOU ALIVE. If you must, search the fourm for your answer, or even ask me. I'd be glad to help!
