I just found out that Dorchester Publishing is now accepting full manuscripts by email. How cool! At the 2006 Desert Dreams RWA conference, I met Leah Hultenschmidt of Dorchester. She is very nice. Three rejections later, I still have her on my dream editor list.
That means I have two houses I can submit PlayFling to in full electronically while I query agents and publish on Scribd.com.
I looked into Jexbo.com. It is for self-published book distribution. But for print only, not electronic formats.
