This is one of my favorite extensions. It combines some of the coolest gallery features I've seen in one download. Install was fast.

After playing around with several of the other extensions and eventually phpbb for 2 days, I stumbled upon this extension about 30 minutes ago. It was installed and configured within 5 minutes. It took another 5 minutes to edit the css to match my site.

Kunena, Agora and the others were far too visually styled and complex to be useful. I next tried phpbb and had trouble authenticating users.
