YES.Some nicks contain this: [EU][RO][ISP].all kinds of this.The point is NOT TO LET the users with those nicks in.Just simple nicks

So you want a script that checks whether nicks contain letters and numbers (and underscores) only?

Try this... not tested.

function MyINFOArrival(user,data)
local _,_,nick=string.find(data,"%$MyINFO %$ALL (%S+)")
if nick then
if string.find(nick,"[%W^%_]") then
user:SendData("NickCheck","Only letters, numbers and underscores are allowed in nick!")
end
end
end
