Creaking From Bottom Bracket I'm not too familiar with the correct terminology for bike parts so please bear with me.

I recently bought a mountain bike and have started to notice a loud creaking sound coming from the pedal/bracket area.  I have noticed that it makes noise when I put more pressure on the pedals from accelerating from a standstill.  I also hear the noise when I am riding while standing up.  

Any tips, suggestions, or knowledge on the matter would be greatly appreciated.
Assuming nothing is wrong with your frame, your bottom bracket probably needs to be properly greased up and re-tightened to the right torque specification.

Frankly, unless you're interested in rolling up your sleeves, buckling down and familiarizing yourself with bicycle mechanics and purchasing all the necessary tools, just take it to your local bicycle shop and have them tighten things up for you.
