bbPress.org

When users enter their topic in my bbpress forum, they have the option to fill out tags as well. Since my forum is running for several years now, a lot of tags have been created. They all result in their own tag-page. Several topics are basically one and the same (for example <h1> and h1).

Therefore I’m looking for a way (preferably via a plugin) to let the user choose from the list of existing tags, while typing their tag. Some sort of autocomplete or suggest function. When they can’t find the appropriate tag, they should be able to fill out their own, new tag.

Are their any suggestions or people having experience with this?

Thanks!
