Generally, if no one replies to such requests around here, it's because no one has the time or the background knowledge to help you out. Your first post hasn't even fallen off the first page yet; it won't have died from being unnoticed. Chances are, I'm afraid, that no one is able or ready to help you at this point.

Also, if I may be blunt, this is a community, and as such, we tend to be more inclined to do favours for each other when we have some familiarity with said people; given that the only threads you've taken part in are related to your request, that makes it a little hard for people to get to know you. In fact, I'm still not clear on whether you want to join our community and enjoy the PPC for what it is, whether or not you write missions, or whether you're just here because you heard that we're good beta readers. If the former, I would suggest actually taking part in more discussions. If the latter... you're not likely to get much of a response. Solidarity and all that.

All that said, I'm afraid I can't help beta read for you - I've never even heard of the fandom, and I'm very busy just now. Sorry.
