Writing about this a little late, but a few days ago I finally tagged the 2.0 release of phpbb2drupal.

The 2.0 release imports from phpbb3.x and the final slog of bugfixing should allow for better clearing of extra tags from phpbb, and also allow for the threading data from phpbb private messages to be preserved.

I appreciated all the help I got in the issue queue too. All in all a good release - especially considering that I do not use the module (last time I needed it was over a year ago, but I have done an import for another person once since too).
