When you make a “test post”, please make sure to delete it after testing! Also don’t test the flagging system unless you are an administrator. This also includes the Vote To Collapse Post feature. Most other testing features are allowed, but please make a post, do your testing and delete the post. Also if you test too much and don’t do the actual forum posting, you could get a forum strike, a coding hut strike, a temporary ban, or even banned for spamming / testing too much!
However, you can still use it normally when needed.
