Hi,
I have set up a Review Board instance[1] for testing / evaluation /
whatever-you-want purposes.
If you are not familiar with what happens in a review, there are a
number of established Review Boards to look at.[2]
This instance is currently configured for gentoo-x86, as well as a
couple of overlays (but it is trivial to add more so let me know if you
want your repo added too).
While there are a number of options available, I personally like Review
Board because it's unobtrusive - it does not disrupt usual workflow
because it's only used when wanted. Have a try and see what you think.
Best regards,
Michael
