UPSB is the initialism for Universal Pen Spinning
Board. It is a message board
created by Pentrix's webmaster
whom to many is known as Kam, and he is also the admin
istrator of the Board. It started out as a small community of proficient pen spinners, and stayed that way until Kam's promotional video for Pentix and Pendolsa's first and most popular collaboration video spread virally around the Internet. After that, the board grew quite rapidly and soon became what it is today.
UPSB could very well be the largest community of pen spinners outside of South Korea, with a total of over 4500 registered members. Being universal, members come from all around the world, are generally very nice, participate in trading of pens with other members, and are willing to help new members learn fundamentals and tricks.
In October 15, 2005, Kam officially closed down UPSB, and will open UPSB again once it has finished upgrading to the new and improved UPSB version 3.
UPSB and Pendolsa are the two largest pen spinning communities in the world.
