Further in the code you have a Switch function, it's like an if then else structure but a lot simpler. As you can see after the Switch you have an enumeration of case "xxx@yyy.zzz" foloowed by a call of the Repkace_Text function. The number of the cases can beeverything you want. If you want that your contact see your messages gradient you just have to add
code:
case "aaa@bbb.ccc":
Color1 = "#0000FF";
Color2 = "#FF0000";
return Replace_Text(Color1, Color2, Message, MsgOutput);
break;
This must be done for every contact you want to send gradient messages to. If you don't want a contact to receive gradient messages, you just have to do nothing, it his adress isn't in the "case" list, he won't receive gradient messages. That was what I meant by the cases list.
