We have just changed our forum software. phpBB has been suffering too many security issues recently so we have decided to move to another solution. We had to change a little bit quicker than expected (old URL not working anymore which is painful for google user, integration not completely made with the main site, etc...) but this should be improved in the coming days.

There are a few good points however:
  searching the forum should be a lot easier with a search box directly integrated in all pages
  possibility to add sub-forum to have really specialized one.
  no post or user data should have been lost (except avatars but they were not activated except for a few users)
  less load for the server
  less security issues so more time to post for us!

Please report any issues to me with this new platform as I could not test all features....
