i don't know why you should be hounding other players for their private add-ons.
i mean, yeah, a couple private add-ons released would be nice because they do cool stuff but i mean.. they're not entitled to give it to you, are they? so why should it be expected? and lots of private mods are very narrow in what they do with very specific aims that only work certain specific ways, and if they were set to be released public, not a lot of them would even exist because of the add-on creators having to make them handicap-proof?
