This question already has an answer here:
I thought it would be fun to see a list of ways to have Mathematica notify you when a long evaluation completes. There are a few posts up already that address specific methods, given below, but not any open invitation to list ways one is or could be notified.
Previously mentioned methods:
Make a noise (such as
Customize the front end (to notify using Growl)
Send an email using
SendMail[...] that can include results in the body or as attachments.
What else do people do? I'm interested in both the practical (what people routinely use) and the fanciful.
A note to the moderators: this thread was previously closed, citing the email link as answering the question. It doesn't; it just gives details how to automatically send email. This post is about new/previously unposted methods.
