Would it be feasible for Steam to make it so that, when you post a thread to the forums, you can customize the thread to behave differently than normal?

For instance, a thread with a rule that doesn’t allow/only allows links, limits the number of embedded videos, limits the character count for a post, disables editing, consecutive post cooldowns, etc.

Do you think this would be a good idea?

A set of custom rules would be limited to a single post and if people didn’t like the rules it would just die from nobody using it, I figure.

Would probably also have to make it so that the ability to do this is turned off by default and toggleable by whoever manages the subforum/game hub (could probably also allow them to adjust the settings hub-wide if they wanted)
