Hello! I'm not sure how this would be possible... But. I think it would be cool to have the option to "watch" a certain prefix in a category. For example in the design section, only be notified via email if a thread is created with the prefix of "requesting". This would make it easier for sellers to get notifications for only when someone is in the need of something made. This could also be helpful in almost every other section of the forum. Thank you!
