Someone wanna give me a tutorial about how to use DropBox as the redirecting service?
only difference being you need to use their client app for transfers.
This part of your post confused me, for anyone else who decides to use dropbox.. you can transfer the files to dropbox however you want, I found it easiest though to download the dropbox program because you can just copy your maps folder (and textures, etc.) into the public folder on your computer and they upload, nice and simple.
