I've replaced my commenting system. Enetation was good, but a little rough around the edges, and a little flaky (did you notice that for a while the (react) link on the Firebird entry below said "(undefined)"?). And as I mentioned in my original post about enetation, I would rather have hacked something together myself. So now I have. Reactor (as I've called it) is online. You shouldn't see much difference, but let me know if you do!

Details: it is written in PHP using MySQL, and I've imported all the old comments from enetation, so all of the comments are now in Reactor.
