## Planet Mongo guestbook / comment features.

Planet Mongo has some super handy comment and guestbook features. By using "Planet Mongo commands" you can insert a place for user comments in ANY content file or news file. It's super easy! Just use the format <!--[[ comment : main : UNIQUE_FILE_NAME ]]-->, where UNIQUE_FILE_NAME is a unique name for the XML database file that is to be created in the config/xml/ directory for your new comment. For example, one might use: <!--[[ comment : main : site_feedback ]]--> to create a feedback spot.

### Add your comment!

The "comment:main" command is actually a short-cut for calling two separate Planet Mongo commands in sequence. These are "comment:show", "comment:commit", and "comment:form". The first shows the comments that have already been submitted, the second will save any comments submitted by any forms, and the third will present the visitor with a form to submit new comments. You can call theses other Planet Mongo commands directly with the same arguments to achieve other results, such as having a comment form that only an administrator can see the results to (put the "show" under a "user:protect")! Another very useful technique, on that is actually used in this page (you should open this file "content/comments.html" up in a text editor!), is to protect the "comment:commit" command with a "captcha:catch" command. "captcha:catch" will help protect your comment page from spamming bots with Planet Mongo's built-in (and ultra versatile) CAPTCHA system.
