In general Page Links To seems to work well. But, I can't seem to get it to actually do a 301 redirect. It always seems to do a 302 redirect, whether the option to do 302 is on or off.
I'm checking the redirect headers with redbot.org.
I've tried it in a clean WP3.0.1 install, as well as an existing WP2.9.2 install.
