Well I am sorry if I sound rude, but generally I've GM'd RPs for quite some time now, and these little mistakes I know for a fact are what kills RPs.

Where I came from, these kinds of mistakes would lead to them being immediately dead. No chance at revival after even 2 days if no one posts. Seriously. You are lucky to have players who are still coming back to this and posting whenever they can or feel like it (which happens to also be whenever they can).
