Since early 2016 I have run Merryn and its various components as a hobby in my spare time: Merryn Music, Merryn Music Feed, Merryn Charity, Merryn Books and the annual Christmas Gift Guide.
I've never accepted payment for people being featured, but it does cost me to run Merryn, so someone suggested I set up a Ko-fi account in case people wanted to say thank you and also to help towards running costs :)
In April 2020, as a resuit of the Covid-19 pandemic, I created the Remote Access Experiences (RAE) website, showcasing online events taking place during lockdown. Again, I run the website as a hobby in my spare time and I don't accept payment but it also costs me to run it, so Ko-fi seemed like a great idea if people wanted to say thank you for anything that I do :)
