For 3 years, I have not allowed general comments (only from our pre-approved, registered users). I am considering opening up comments to all; hopefully, to boost traffic and interaction on the website.
I have never had open comments. Can the community offer any suggestions about how to best go about this? I want reduce or eliminate spam, cursing, offensive language, etc.
Any suggestions are greatly appreciated. Plugins? Black Lists? Comment Requirements (email, name, etc.)? Other techniques?
