basic hedge fund info needed

[btmagnetw]

i have 0 knowledge about hedge funds but am in need of some. google and wiki are giving a lot of general information about what they are but i need some more specific info.

among what i need to know are:
what are carry charges? what is aggregate carry?
is your interest solely calculated based on your contributions? how does withdrawal work?
are hedge funds usually set up as partnerships? how is setting one up as a corporation different?

if you have the answer to any of these i'd appreciate it. if you know a link that explains some of the more complex issues, that would help too.
