I'm happy to announce that Derek Vogelpohl - of ShyFonts/ShyFoundry - is now also onboard! :)
He has just recently re-opened a webpage where he offers his free and commercial fonts again, but I asked him if he was interested in my concept. He was, I reworked one of his fonts, sent it to him, and he liked the result - so now I have his huge library of quality font designs available to rework! Yay! Thanks, Derek! :)
(The sample font I made for him will be available very soon ;)
