The 2025 Heavy Harmonies Donation Drive!

The annual donation drive covers the site expenses, which are up this year, no thanks to an unexpected forum move, which incurred a fair amount out-of-pocket expense. The drive will run through the end of the year, details over on the Heavy Harmonies Forum.

Every donation helps, no matter how small. If you can't afford $20 for the year, give $10. If you can't afford $10, give $5. It's just once a year and keeps the lights on.

Thank you for supporting Heavy Harmonies!
