I've done this before, but i forgot how to. I know you need everything you want in the pack in a folder, and you need WinRAR or WinZIP. i have WinRAR. So, how do i zip it or whatever it is you do.
right click whatever you need to include in the .rar file, and choose add to archive or add to xxx.rar
If you need it hosted, http://filefront.com and http://ripway.com are ok sites to hsot stuff like that.
and that was spam anyways, even you dont need winrar or winzip... Right click on file or folder then Send to-->Compressed (Zipped) Folder winrar is just nice, cuz it has best compression and u can add password to it too
