http://www.feed-the-beast.com/ download that. I believe you download the Jar, and run that. it will open a new launcher, and give you many more mods than you could ever want. Most mods you find on the fourms are 100% safe by the way, so tell your father as long as it is from here, it is reliable. i have 58 mods directly from the fourms and im loving it up.
