I don't want to be mean, but some of these plugins have a license that must be purchased and sharing them is not legal. Moreover, some of them do not want any intermediary in their distribution. You should provide a list of them with links to the original pages or threads, not the files itself.
Hey @fizzlymike, no problem, thanks for the warning. At least at the time I used these plugins, they were all allowed for commercial use as long as they were mentioned in the game's credits. This may have changed since then.
