Concerning the question of the credibility of the Baghdad blogger; Paul Boutin has made a detailed assessment of this and concluded that yes, this probably is legitimate. The name Salam Pax, however, is false (the two words mean 'peace' in Arabic and Latin respectively).
I found this link at Wil Wheaton's blog. I thought you would appreciate it and might be able to put it up on your website. I don't know how many people will be able to do this but it's a great idea.
I was just reading through your blogg and I noticed that you have Denmark on your schedule for your upcoming tour of Europe.
Will you be publishing a date, time and place for your Danish appearance in the near future?
Sure. I'll put up all the European dates very shortly. I think Denmark is in the second or third week of May, following Poland.
