Rules of S&I
Users are encouraged to post suggestions within certain parameters. These parameters are commonly known as the What Not to Suggest (WNTS) rules. Most of the parameters listed within the What Not to Suggest rules include suggestions that either will not be implemented into future features, such as getting rid of Builder's Club or adding an AFK system within all games, or suggestions that are frequently posted and have been acknowledged by the administrators, such as adding voice chat and pets to the game. Sadly, very few posters have actually read WNTS, which results in the posting of several redundant threads.
In addition, all users are expected to follow ROBLOX's general forum rules and to be respectful to all users within the forum.
Making a suggestion

Though users are not reprimanded for not following this thread, users are encouraged to read and follow some of the suggestions posted within the thread. It is also encouraged that users are open to feedback and criticism when suggesting an idea.
