Well...you made your character virtually an identical copy of my posted character, with just a couple of tiny differences.
That's not ideal from my perspective.
I don't feel like I have any authority to ask you to change your idea, but...I'd be lying if I claimed I didn't feel put upon. It's not like my submission wasn't on the site, on the very same page in fact, that you posted to. It was like...two posts above yours. You didn't even have to look back to see it.
But do what you want. Having some second thoughts about joining at all, truth be told.
