Seems easy enough... just use the WordPress Rewrite API to change
mysite.com/login/ into mysite.com/wp-login.php
(This would make things a lot easier for new WP users to get to their dashboards.)
Ozh's plugin works nicely for regular WP, but getting it to work on MU to be a common problem. If you read the comments on Ozh's plugin post, there are lots of MU users having issues getting it to work.
I'd like to request a multisite-compatible version of this plugin. WPMU DEV has the technical knowhow to get these rewrite rules working for multisite networks.
I have tried Ozh's plugin on both our production server (Nginx, multisite) and my local MAMP install (multisite). Neither worked. I'm getting 404 errors when trying to access mysite.com/login/
James? Aaron? Any takers? Any +1's ?
