Very simple, quick and surprisingly effective: add a donate button by clicking on the options below your Facebook post text. Click on 'support non-profit' and find PSC Support.
You can also create your own special Facebook fundraising page by clicking on the '+ Create fundraiser' tab near the top on the PSC Support Facebook Page.
It's wonderful to see people do this on their birthdays. Perhaps you don’t need gifts, especially when that money could be spent in a much more meaningful way.
