Is there a way to donate?

I've been looking for something like this for a long time and have really enjoyed doing the problems (wish I could more of these types of problems, but my last USAMO was over a decade ago and most similar contests seem to be gated to students only). Was curious if there was a way to provide support this outside of volunteering (I'm pretty terrible at coming up with problems). Any costs that this work is incurring (e.g. keeping the website up, advertising on platforms, maybe one day an app) that people to donate money to?
