I'm sorry, but to my best knowledge, the Codidact core team has no millionaires.
We don't even have a common "Codidact bank account", because a certain pandemic has made it much harder to open one than we thought.
We already have a way to have Codidact t-shirts produced and we might even do another swag event at some point in the future (without committing to anything). However, unless we have a bank account and/or funding, we can neither sell t-shirts nor give them away for free.
Side note: If you really want to help us, registering as a UK bank and offering a bank account to us is probably the most effective thing right now ;)
