The only reason I can think of for submitting anything now is to get feedback, so if that isn't on the table I think you're probably right to let it pass. If, however, they are likely to reply with critique it might point out flaws which you have thus far been unaware of.
Of course, Chrons serves an equally valuable function, so maybe just save yourself the effort and post it here as you go - as you are, in fact
No. I thought it was ready. One can't afford to waste the few SFF agents that do exist. Oh no no. But now I'm introducing a whole new section and inclusion to the book, so to speak, and that brings out other stuff all the time, one thing leads to another, you know? Erlos matters to me as more than just a story, it's a statement and a legacy, sort of thing.
Thanks
