Fantastic that you want to apply to the preview program.
codeRR OnPremise contains enterprise features like better team management, Active Directory support and built in integration with Team Foundation Server (TFS). But also triggers (filters and actions), an improved duplicate detection algorithm and better possibilities to integrate codeRR with your local systems.
We are however looking for dedicated users that will really put codeRR to the test and come with feature suggestions and improvments.
Are you that person?
