I don't maintain that collection, so don't lynch me if something has gone down (just let me know so I can remove the link).
I'd like to get back to writing the newsletter stories; I mainly stopped because I'm spending all my time either writing or working on business stuff, but now that I have minions to handle my business business, I'm hoping to revive the short stories soon.
You ever write a word so much that it starts to look weird? Business.
Can I be a beta reader?
Not unless I know you. I typically keep the beta readers to a pretty narrow group, and I only introduce fans into that group very selectively. There are 4-5 members of the beta team that started out as fans, but I still had to vet them personally before I allowed them in.
This is mostly to avoid concerns about the manuscript leaking or my undead curse spreading to the general populace, but it's possible that I'll change my policy in the future. I may do a contest or something, from which I select a handful of beta readers.
But I'll announce it if and when that happens. Till then, no early copy for you.
