I just tested the code, and i agree, you need to explain in description, i didnt know i was supposd to right click a nick

few errors:

giving blank reasons screws up
u didnt check for op
*duznt put address in dialog

again, i highly suggest using a hash table or ini, because with a txt, you can add the same nick twice, which isnt needed

also, it would be nice if you update the dialog when you add ppl
