Another writing milestone!
Actually, I wonder if the letter of acceptance would work as proof of sale? Cricket can have up to a two year lead time, and I know from my previous sale with that publisher that they won't send the contract out until after I approve the edits. And I'm pretty sure they don't do the edits until they've got the story scheduled for an issue. Hmm. I'll ask the folks at the Rumor Mill. But I suspect I'll have to wait for the contract.
*twitch* But in a good way.
