I'm very sorry for the lack of activity but I have some fairly bad news!
Our clan has entered ETF2L and so I can no longer use the private server for testing (with the feedback system anyway, etf2l rules forbid extra plugins like this). We have a 2nd private server (32 slots) which I was planning to use instead, but our clan has agreed that we're losing too much money on that server and so it will also be gone before too long.
I'm truly very sorry for the inconvenience, I will still do my best to get the feedback system to a working state that I consider suitable for public release, in the mean time I could attempt to do public map tests on our public server, though I'm not sure how much good that would be if these maps are aimed at the competitive scene.
