[Foss4g2009] Errata - Presentation Bios

[Cameron Shorter]

Volker,
What process do you suggest we follow to allow people to change their 
abstracts and bios?
Is this something you would be able to facilitate?

Ideally, I'd like to open up the abstract software for 3 weeks or so, 
allow people to change their abstracts, then at the end do a bulk update 
to the website.
