Thread:Extension talk:BlogPage/Captcha to Comments of the BlogPage-Articles

Hello MediaWiki friends I have a question for the blog Page extension. I installed it and have seen that guests are allowed to comment specifically as anonymous.

I fear that there will be a lot of spam because you have no Captcha in the comments. How can we Captcha used or how can I deactivate comment for guests?

Can I perhaps someone help?

Thank you in advance.
