Attach screenshot

Sometimes a picture says more than a few digital lines. Take a screenshot and show us what’s wrong. We can analyse your problem better when you add a screenshot.

We accept the following file types: pdf, jpg, jpeg, png, gif or bmp.

How do I take my screenshot?

On MacOS:

Hold down COMMAND + SHIFT + 3 to take a screenshot. Your screenshot will be saved on your desktop.

On Windows:

Press PrtScr to take a screenshot and it will copy to the clipboard.
Or you can use the snipping tool to capture screen shots (Snipping tool Windows)
