On the Topics page http://perl-qa.hexten.net/wiki/index.php/Oslo_QA_Hackathon_2008_Topics I have started to move the topics suggested by people to a separate place and started to include a list of interested people.
I think the talks can be removed from this page as they are already available on the main page and we should collect only the topics and 'sign up' for each topic in which we are interested. Later we can also reorder the topics according to importance/interest. Right now they are there in a semi random order. Gabor
