Some users may have problems printing pdf files directly from their screens. This is a problem with some current browsers and operating systems. If you are affected, please save the file(s) to your computer – usually by right-clicking the link and choosing Save As, or similar – and print them from there.
This also applies to the poster on which you can fill in your Group name and the time, date and place of the litter-pick you are organising, and the ‘Just Cleaned’ sign where you can fill in the name of your Group. You may find you cannot enter the details when the form is in your browser, but it should work if you double-click on a copy saved to your computer.
