I've not done this before but I'm posting this on behalf of one of my sons. It's a worthy cause.
"I'm working with Good Neighbours UK where they have just started a small matched-fundraising effort and I wanted to share it here in case you'd like to help.
We’re working with our Zambia team to build proper classrooms for a rural school where 335 children are currently learning in makeshift shelters. For this campaign, every pound donated will be doubled, so even small amounts go a really long way.
here’s the link If you’d like to support (or even just share it):

Any support is greatly appreciated so thank you."
