Some people who develop things for their mod do not do so for everyone to enjoy, just for the people who play their mod.
Considering how easy it is to find out said things by looking through the mod files, it's actually just asking for trouble.
If everyone just kept their knowledge to themselves and didn't learn from each, from reverse engineering etc as Treewyrm said, then Freelancer modding would be still be back at the beginning.
Advertising Disco on other forums is ok by what Maj said, just as long as it's within the guidelines of the forum that it is posted on.
In any case, go to the Starport if you want modding help or ideas or even to pick up new things really. The people there generate a far more friendly atmosphere for sharing ideas and modding things than I've encountered elsewhere.
