Hi ... first of all thanks for trying out the plugin and for getting in touch. I've been wrapped up in my day job for a while so I haven't had the chance to catch up with the forums here.
But ... support for the
[wp-biographia] short code is now part of WP Biographia v2.0 which, as of this morning, is now in beta and available for download from GitHub at https://github.com/vicchi/wp-biographia/tags. See http://www.vicchi.org/2011/11/01/wp-biographia-v2-0-goes-into-beta/ for more background and information.
If you don't want to manually install the beta version onto your WordPress install, once beta testing is done and dusted I'll be updating the WordPress plugin repository so you can update automatically via the dashboard.
Once again, thanks for using the plugin and thanks for getting in touch.
