Matt showed us the undo tab in Gmail and how you can send an email to anyone and if for any reason you may have forgotten to add more to the email or want to undo an email then you just click on the undo tab but , you have a choice of 10, 20, or 30 seconds to undo. So we got to play around with the undo tab. I sent Matt an email but I couldn't find the undo button quick enough and the email sent (oh no). An apology email soon followed.
I invited Matt and Dorothy to a Hangout conversation on Monday and for a laugh I wore a wig. This is a screen shot of our Hangout.
