I've set up a reviewboard server:
Right now it's not that nice to look at, but next version of the software will have theme support. I've also added a 'yt review' command to the trunk:
$ yt review
will submit a subversion diff of your entire current directory to the server; you can also specify which files you want it to submit diffs for, and you can update existing diffs, etc etc. I might have committed some errors, but the primary function of the script works, so it should be useful for us. I'm still working on getting the emails to send out.
I'd like major changes, as well as changes to deep and relatively wide-reaching machinery, to go through here before they get committed.
Let me know if there are any problems -- and there might very well be, because I'm still new to the review board software. :)
