While conducting some research today, I found that as of August 2009, the jihadi forum Tajdeed.org.uk is back. The website was one of the most prominent – if not the most prominent – jihadi discussion forum until it went down about a year and a half ago. The website’s administrator was and remains Muhammad al-Massari. After Ekhlaas and Faloja, it seems it is all the rage to bring back shut down jihadi forums.
One of the most prominent Englisch forums perhaps. In that periode al-boraq, al-firdaws al-akhlaas and al-hesbah were the main AQ forums.
Very active now, and one of the few that remained up last 9-11 period, is the English ansar-al-jihad forum.
