Personally, as a PR, I really don't think we need help.
I'm almost always on Skype if a PR is needed and can get on VC any time I'm called, and the few times I'm unavailable, Kovos is available to step in.
Plus, right now, PRs are limited to staff abuse cases. We don't do much with reports about griefs because the staff handle that now. Seeing as the only "staff abuse" I've heard of was Sax not really getting Air's humor and feeling the need to report his joking, we're basically just there to look pretty [and boy, do Kovos and I have that covered
]
We're very grateful for you wanting to help, don't get me wrong. It's very nice to you to offer. But for right now, I'm thinking that the best way for you to help out is to keep following the rules, offer help to new people who ask questions, and just continue being a great player
