It is very simple even though the page is in Slovene.
Go to http://objemtopline.dormeo.net/ and scroll down to number 10: Društvo za pomoč Obalnim mačkam Mačja Preja-
Click on the green button under number 10 that says: "podarim objem" (I am donating a hug). A window will pop up the first time asking you for your e-mail address (it won't be used for commercial purposes).
Write in the e-mail address, go to your e-mail account and click on the first link in the text of the confirmation e-mail that you will receive within minutes.
It will redirect you back to the voting page, where you click on the green button under number 10 and an added vote should be seen.
You can than simply click every day in March. If you have more than one e-mail address and more computers or smartphones, you can vote from each (with different e-mail addresses of course).
Thank you for helping! Every vote counts!
