Oh jeez... not again. I really don't feel like explaining it all again... but let me just say that telling people not to use their throat is fucking stupid. And neve push with your stomach! This is where everyone gets fucked up is these two points. You just have to growl like a dog, basically, and learn how to go up adn down pitches with it, and sustain it. This takes time and effort. Your voice must be strengthened through frequent use, but you have to be very careful not to overdo it, or your singing voice will be out of ommission for a few days. Remember: never force the sound out! It should always flow and feel good, or you're doign it wrong and harming your vocal cords. You must breathe in quickly and deeply, like when you're scared (makes a "huh" sound)... then let teh air slowly spill out while singing. If you suddenly lose all your air, you've collapsed your diaphragm and will need to get more air almost immediately. You just have to experiment for a long time to find out how your bodyw orks. Searching the internet for singing tips will probably turn up soem good sites, I know it has for me.
Okay that was just a quick run-through but I didn't feel like typing.
