Hope you feel well soon, and definitely watch your back around someone not willing to offer a contract. Smells fishy to me. Go with your gut. Is the sale worth getting potentially burned? And maybe you insisting on a contract will help him realize that, yes, there really do need to be such things.
And the editor had no problem agreeing to my contract, so I've got peace of mind on that front. He's not the only editor I've run across that didn't have contracts, either, although those folks are in the vast minority. In such cases, I've assembled my own--something incredibly short and straightforward--and I haven't had a problem with any of them. You'd think that everyone in the biz would be very contract-conscious as it protects all involved. I believe this market only recently became a paying one, which might excuse their lack of contract savvy, although I would still expect even 4theluv markets to do contracts . . .
