Pl help me for the comment input format for site comments

I want an input format for comments for site visitors who will not use html. However all line breaks should be retained and html special characters need to be escaped开发者_Go百科 including the hiding of email ids.

Can somebody tell me if these settings are ok and will not affect my site in any way ?:

yes, it's totally fine. Don't forget to apply this format as default for comments.
