Thanks, that's great! I'll start using that.
I have another, smaller related problem with urls.
I can't do this
(r'^blogs/([_A-Za-z0-9-]+)/', include('bloghost.blog.urls')),
because then the captured bit after blogs doesn't go anywhere.
I have to do this:
..
(r'^blogs/([_A-Za-z0-9-]+)/', 'frontpage')),
(r'^blogs/([_A-Za-z0-9-]+)/feed/', 'rss')),
...
Which is fine really, more of an itch than anything else, but it'd be
nice to do it the Right Way(TM).
Thanks,
Frankie.
