I'm aware that probably nobody will pay attention to this thread, like it happened the last time I requested this.
I integrated wp-login.php and profile.php in my custom theme. That it's to say, I load my custom theme css file, header, footer, sidebar...
To do this, I had to change the code of wp-login.php and profile.php. It is not difficult to do, but each wp upgrade is a pain. Even more painful in 2.5 because profile-update.php disappeared and there was a call for user-edit.php there.
I can't believe that a bunch of new useless features are being impleted for 2.6 when 5 years later there is still no template for a simple login page and a profile page.
BTW, a step forward would be a blog software with an integrated forum, you already have the blog, you already have the forum -bbpress- and you already know how to integrate both of them. Why not to release the whole package once for all?
