Emailing or forwarding of email jokes is a full time job to some. If you still need to forward these (I do too), remember to try and make the email “your own”. Depending on the recipient’s email program, or service, these emails which have been forwarded countless times are either 20 screens long, or are nested 20 emails deep. Sometimes, and quite often, not worth the effort to finally see the picture or read the joke.
If you get a good picture or joke and feel the need to share, Copy & Paste just the picture or joke into a completely new email.
Also, keep peoples privacy by NOT putting everyone you know in the TO: field.
Here’s a trick, Put yourself in the TO: field and put everyone else in the BCC: field.
