I've always thought that mold is the fungus, and to mould is to shape. When talking about it with my colleagues yesterday, I was surprised that this isn't common. Most people use one of the two spellings to refer to both.
Doing a quick search on duckduckgo also confirms that:
- mould is the British spelling referring both meanings.
- mold is the american spelling referring to both meanings.
In my quest to prove them wrong, I was surprised at how wrong I was... until I discovered a few people on the internet who said the same thing:

I'm not looking for what's correct or incorrect anymore, I just find it very fascinating that there are some people who use the words similarly to me, but the vast majority of others who use it in a different way.
So: what's the difference between mould and mold according to you?
There's a fair number of people who insist that "geek" and "nerd" mean two different, specific things. I think this is the same phenomenon, that people seek nuance where there isn't because it makes the language seem more interesting or something.
The words have very different origins. While I think they converged for a time, they started out different.
