There are a lot of different ways to "bump" your question (or others that you're interested in). One way is to edit it **adding more information**, like documenting what you've tried, more data about the issue, etc. Performing minor edits just to bump your question will eventually make the question a Community Wiki and you'll no longer gain reputation on that question.

If you've added everything you possibly can, you have the ability to add a [bounty](https://askubuntu.com/faq#bounty) to a question. This adds the question to a [list of featured questions](https://askubuntu.com/questions?sort=featured) which users browse and answer frequently.
