uploading a new module

how do i add a module i have created to the list of module’s so that people can download them? (mainly i need to give the beta of my game to my friend so we can play test)
do i contact some1 or upload to a specific place, because i cant find out any info on the subject…
many thanks =)
also could some one tell me what or how exactly you get the module you have created into a state where u have all the information for the module (such as folders and what not, or whatever you need) ready for upload; do you need to do something special or is everything in the 1 file you create when you make your module?
i cant find any info about the subject in the tutorial or help page
