Show HN: Konkourse – Taggable group discussions with anonymity option

konkourse.com is a side project of mine. My goal in creating this application is to provide a simple way for people to create public or private discussion groups that are easy to find (tagable), where users can choose to contribute under their identities or anonymously.

I've also provided a simple tool to combat trolling: the group owner can identify anonymous comments and block users from posting anonymously in the future.

I would appreciate any feedback on the overall site design, experience using the application, and general thoughts on it's usefulness.
