I don't think this is CUSA actually. This is apparently done by one Buffo Luciano, and I don't recognise that name from the CUSA staff (all three of them).
OT:
To be honest I think they've all given up and gone home anyway. The forums seem to be run by one person, Barry hasn't posted on the forums since August, last I checked - there's no "Amiga" range available any more at all, and I don't even know if they're still selling the C64x. I think there's only Leo doing anything these days, by reskinning Linux Mint.
