The newly revitalized UPSBv4 has a great new feature: Prefixes We've added prefixes for almost every community in the video sections, in order to make a thread you must add the prefix of what community the video is based from. This has several advantages. The biggest of which is, if you wanted to watch only JEB videos, you filter the section by prefix JEB. Same for UPSB, or any other community. Happy filming, and everyone represent your community! :)
