Just a few questions.

1. How do I take a picture in crossfire? (I've done it a few times by accident, but don't really know the correct key)

2. Is there a way I can take the replays on saved on crossfire, and put them up on youtube? When i try to watch the replays outside of crossfire, my Windows Media Player says the files are in a format in which they can't be read in, therefore, i cannot watch it on windows media player.

3. This one is hard to put in a question, so I am going to give an example
If you look at the power of an Ak 47 and the AWM, the Ak's power bar is right under the AWM, but yet, it does like 1/3 power of an AWM shot in 1 shot. So why does the AK's power bar fall right under it, when the damage in 1 shot of an AK, isn't as close to as 1 shot of an AWM.
