I found this in one of my first scripts, pretty much a notifier/greeter. When someone on your notify list joins a channel you're in. It will greet them.
I.e.

--->°Notify Alert: slack[photon] is online.
° Join: slack[photon] / !JSaprvd@XXX.XXX.XXX.XXX / #souless
|4:41a|            |(@) morbid | WB slack[photon] Heyyy

I do know I could have set it into a text file, instead of variables. But what did I know ;/
