App suggestion please: blog / forum software in Python

[stewart.midwinter at gmail.com]

thanks Kartic.  I use Frog already at my office.  For this particular
application, its design may not be appropriate, since each user gets
her own blog space.  I'm actually after a community blog, where any one
of the registered users can post an item, or discuss on a forum.

Drupal, from http://drupal.org, seems to do exactly what I want, except
it's written in php.

Thanks for the tip on Vellum. I'd like to find a few sites using it, so
I can see it in action.
