For those on the end of a support line, trying to replicate issues that are reported is often a problem. The same applies when your staff need to be informed as to how to do something using a software program. A detailed list of instructions with screenshots and text is one solution, but this can be laborious and time consuming.
Recording a video to illustrate the point is often far quicker.
Loom.com allows you to record your screen, and send a link to any recipient, and this can be used free for videos up to 5 minutes in length.
Use it for other purposes too – training and instruction, how to etc.
