Also, if you plan to hack a lot in WordPress, CenMayo’s WordPress Crossreference is handy to have. You’ll probably soon find out you can’t live without it anymore. Someone should make a html version out of that so you can browse it locally. Go figure.
I probably already linked to it before in my Elsewhere links section (which can not be shown individually, until I find time to hack and clutch something together). Uh. I’m busy.
