Not crowdfunding. Oh no, not us.
Crowdfunding would attract income tax in the UK (unlike the US, where it's hugely popular and a great way for people to help each other - anathema to the UK tax system).
So it would be completely inappropriate of me to set up a PayPal link and invite people to contribute. If I did that, foolishly, then I would be able to keep track of contributions separately from any of my personal transactions and be open and transparent about the accounting. I could also post on here to report periodically on how the fund is doing as well as what's getting spent.
But that would be soliciting payments, so we're not going to do that.
Just to be clear to HMRC, I am not soliciting payments. Not at all. Please don't give us any money. If you are nevertheless moved to make a small gift to express your gratitude at the saving of the last (-ish) road legal grey grille Sierra, spontaneously and without any prompting whatsoever, then you might happen to stumble upon paypal.me/sierrabase.
