I just signed a contract with a small press for the print rights to my first serial, Flight of the Godkin Griffin. Flight was my first go at crowdfunding back in 2004, back when putting an entire novel up for tips was considered bad business. I'm glad I put it up now!

Just remember... just because you're not being paid now doesn't mean you won't be later!
