Topics auto search
Is it possible that if anyone is writing a new topic and before submitting, the system will show similar topics share the same keywords, so this avoids many topics/questions are raised of one subject?
Starting from wpForo 1.5.2 version, wpForo has a built-in Topic Tags feature.
Topic tags allow users to filter between forums and display topics with a specific topic tag.
If topic tagging is enabled, when a user creates a topic they have the ability to add specific tags to quickly explain what a post is about and it also helps users find related topics based on those tags.
