Creating a new one (if it's the exact same thing).
If it's bumped two, tops three times on different days and different times, and there are still no comments, then sadly people don't have anything to say. Happens!
But a bump is still boring. Try to add interesting thoughts, and expand what you wanted to talk about ~ in case the topic is really important for you.
Also, I apologize for starting to ruining the original purpose of this thread, and getting too off topic.
Happy bumping, people!
