The best way to support the multi8it project is by becoming part of it. By watching the videos, commenting, letting me know in what direction you want me to take the project. Have you made any MilkyTracker songs since you watched my tutorials? I'd be happy to have them in a YouTube video, either as background music or maybe more of a radio style video cast or pod cast. Drop me an e-mail or find me at Twitter or Google+. All that info is on the contact page.
Now if you insist on donating money, I will gladly accept it. Once I had Google AdSense ads on the blog, but I figured I won't make any money from it any way. Hence, the only way I will ever make any money off this project is by donations. Below is a PayPal donation link, and Flattr buttons are located to the right and at the end of every post.
