Place holders can be used to direct people to do or not do something. Placeholders will show up in selected forums for threads and/or posts if you desire. Placeholders disappear as soon as the user starts typing in the editor.
Placeholder Example:
Thread & post prompts/templates can be used for a user to be directed to fill in the information in a specific way, This is useful for forums such as a car site. This does not disappear as the user starts typing, but unfortunately the user can edit the text out, there is no way around this.
Thread Prompt/Template Example:
This system works the same for the quick reply editor as it does for starting new threads. Thread prompts/templates will override a placeholder. Meaning that if you gave a placeholder and prompt defined for a forum, the prompt/template will show, not the placeholder. I've seen quite a few people looking for this so I decided to write this up and release it here.
