Can you please google the definition of thread bumping please. I know so many people who keep getting warnings for "bumping"threads which they create... I have had warnings from the mods who say that "bumping"is replying to a comment in the thread which is created is a bump. Wrong.
Please feel free to read this
"Thread bumping" is the act of posting in a thread, with the sole goal of getting it back to the top of the thread list. Some people thread bump because their thread wasn't noticed during a busy time, while others bump threads just because they want to.
Thread bumping in the technical forums happens quite often – especially when the thread involves a problem that the poster wants solved. As such, bumping simply because you posted it at 3am and no-one's replied by 7am is pointless, but bumping your post after a day or two, when you have had few replies might allow you to tap into a different audience.
There are a lot of working techies in here who don't often read WP during the evening/weekend, but are able to give very valuable answers to questions. Bumping to ensure your post gets read by both "shifts" seems ok to me.
In summary: a thoughtful bump is ok, but one that simply screams "waaaaah, no-one's listening to me" is not.
