This is a solid beta. It installed without any problems and everything works as it should so far. The design looks great and I love the ability to change themes. It has many nice features common in modern forums such as BBcode, smilies, user ranking, groups, etc. However, what it is missing is a deal breaker for me. I need a forum with a way to ban bad users (such as spammers and trolls). While you can just delete a user there is no way to ban by IP and there are not many admin options for other administrative tasks from within the board layout. This is a good forum for anyone who wants an easy yet sophisticated solution but doesn't have a need for strong user control.
I hope to see IP banning in the post-beta versions.
