Lana and Josh - Thanks to both of you for responding.
Jenny, feel free to send these links to communitybugs@marketo.com. (community@marketo.com is also an alias, but bugs is better for this sort of thing) and the appropriate person will take care of it. We did a migration a while ago to clean out our help articles, and to move those that weren't help articles into resources. This unfortunately didn't automatically update the old links, so piecemeal we are redirecting them.
Thanks!
Liz
