I personally think that all those all-around mIRC "scripts" are just silly. They are created and used just for the sake of having a modified mIRC packed with (mostly) useless/annoying stuff.
(Somehow this reminds me of that thread about car modding...
)
My "philosophy": Only if you need/want something in particular, find or create the specific code for it. The only use I can find for NNS is learning scripting techniques from it (or stealing a specific piece of code
).
