Installing/loading mathematica packages

[Reedeegi]

How is this done? I have Mathematica 7, by the way.

Hi. First you have to write the package in the correct form, then save it in the packages sub-directory so Mathematica can find it or maybe change the path in Mathematica with one of the directory commands. Then you need to use the command that loads the package in your notebook. That's either << or the "Needs" command. Then just call the functions that you made public in the package.
