Do not bump posts. Bumping a post to “the top” does not help a topic get noticed. The volunteers who try to answer questions look for those without replies first. If someone bumps a post, then it disappears from the ‘No Replies’ view.
We have a list of threads without replies. When a post is bumped, it becomes harder for it to be discovered and reduces the chances of getting appropriate help. Some forum helpers use that list to prioritise over other answered threads.
Moderators will delete bumps they find. This is in order to help posts get back into the No Replies listing, where they are more likely to get an answer.
