The easiest way for me to make this easy for you is to use regex, will look like if ($regex($nick,/(Taw_Sloan|Xariannii)/g) == 1) { }
Now what you are asking about is if ($nick == Taw_Sloan) || ($nick == Xariannii) {}
Can be cheated to do if (($nick == Taw_Sloan) || ($v1 == Xariannii)) {} that way it's always pointing back to the last number 1 parameter in the condition. TOP down left to right in to out can get confusing real fast.
OR with tokens if ($findtok(Taw_Sloan|Xariannii,$nick,124) isnum) {} OR if ($findtok(Taw_Sloan|Xariannii,$nick,124) != $null) {} OR if ($istok(Taw_Sloan|Xariannii,$nick,124)) {}
warning these have their draw backs. You will reach a limit of how many nicks you can manually enter if you're not doing just raw if () || () || () | () {}
Using hash tables,inifiles,binary files can increase this size and can be easily coded to "enter" a new nick to be able to use it etc. There are tricks and cheats and so many ways you can do something like this from very basic to advanced.
