2+ Weeks into The 2026 Heavy Harmonies Donation Drive

Sep. 22, 2026: A bit over 2 weeks into the annual donation drive and we've reached 37% of the goal of covering the site's out-of-pocket expenses for the year. Thank you to everyone who has contributed thus far!

The drive will run through the end of October. If you find the site useful, please consider throwing a few bucks towards it. If you donate $20 or $50 for the year, you can earn a shiny user badge over on the HH Forum

Thank you for supporting Heavy Harmonies! -Dan
